The function PI_Controller() implements PI control but there seems to be an error in the final output with the wDischarge term. This term is calculated at the very output as the anticipated amount the output exceeds the output limit's. The intent is to reduce the integrator by this amount but the code does not account for the Ki divisor, pHandle->hKiDivisorPOW2. Without this the value applied to the integrator is too small.

Hello, I'm using STM32F334C8T6 and trying to measure the duration of my calculation sectionfrom MCMP1R (JEXT9) which triggers ADC1 till all TIMER's D CMP registers change.1) I enabled Global Master Timer Interrupt and MCMP1 interruptNVIC_EnableIRQ(HRTIM1_Master_IRQn); NVIC_SetPriority(HRTIM1_Master_IRQn,1); HRTIM1->sMasterRegs.MDIER |= HRTIM_MDIER_MCMP1IE;2) I made the Master Timer Settings in such way:HRTIM1->sMasterRegs.MCR |= HRTIM_MCR_CK_PSC_0; // 128 MHz * 16HRTIM1->sMasterRegs.MCR |= HRTIM_MCR_CONT;HRTIM1->sMasterRegs.MPER = PERIOD; // 40 KHz PWMHRTIM1->sMasterRegs.MCMP1R = 1024; // 0.5 microsecondsHRTIM1->sCommonRegs.ADC2R |= HRTIM_ADC2R_AD2MC1; 3) And finally the IRQ handler, which doesn't workvoid HRTIM1_Master_IRQHandler(void){ if(HRTIM1->sMasterRegs.MISR & HRTIM_MISR_MCMP1) { HRTIM1->sMasterRegs.MICR |= HRTIM_MICR_MC

Hello all, Currently I'm working with BLDC motor 6 step drive. I'm using complementary PWM channels. Logic works good and working with well with the hardware. But when ever i insert dead time its reducing on time of the Low side pulse (CHxN) but for my gate drive hardware hardware I want dead time should work on high side channel (CHx) Please suggest how to debug this issue thanks Regards Karthik DM

Hi,I'm using a Nucleo -F303RE with X-08 inverter board, and need to enable the SPI peripheral.Code is built directly from the ST MC-SDK 5.4.4, (FOC mode) then examined in Cube-MX 6.0.1. Built in Keil uV5 - no change to project options given by MC-SDK.I use the combined HAL and LL code (where offered) as this produces 5kB smaller code than pure HAL code.Then I enabled CANbus on PB8+9 in CubeMX; "updated" and works perfectly. Full duplex command-control-reporting sub-system OK. Rx interrupts enabled (low priority).Motor runs perfectly, and can be controlled either over my CAN or ST's MCWB console.Then I enabled SPI2 on PB12~15 in CubeMX - and removed R74 and R86 (ZOLs) from the X-Nucleo to de-couple the SPI port pins.Refs: Doc ID028716

I'm implementing a motor control project using a STM32G431 device. The host computer will communicate to the MCU through an FPGA. Presently my thoughts are to implement the serial framing protocol on the host side and I am using this document: UM1052 User manual (STM32F PMSM single/dual FOC SDK v4.3) as a reference. Is this document (2016) still applicable? Edit: added file. The portion I'm interested in is Section 14. Whether this works impacts the PC code as well as the FPGA code.As example I was thinking of having the PC GUI code issue 'SM1' to the FPGA UART to start the motor. The FPGA would then send  0x03 0x01 0x01 CRC to the MCU through the MCU UART. The FPGA will be connected to up to 4 MCU's, each with their own motor and UART interface.

Hello.Please give me some advice.I want to configure IAR project for triple motor control(gimbal) using ST MCSDK.I have made IAR project for one motor position control using ST MCSDK( STM32F303RE + STSPIN233 + GBM2804-100h + AS5048A pwm encoder) and it works well. I want to expand from one to three. So what I thought was as follows.For FOC motor control of MCSDK, advanced timer is required. the STM32F303RE has two advanced timer(TIM1, TIM8). So if MCU is changed with STM32F303ZE(144 pin), 3 advanced timer(TIM1, TIM8, TIM20) are available. But it seems that ST MC SDK does not support triple FOC. It seems that only dual FOC is supported. So, after configure dual FOC motor control IAR project, I'm going to edit MCSDK middleware for 3rd motor. Is this possible? It seems difficult to modify it. Is there any way to solve this problem effectively?Thanks.

hi, I want to make a steering wheel with STM 32, I have assembled (DIY) the steering wheel myself. I use DC motor and BTS 7960 for feedback (FFB). and encorder to determine the steering angle. as well as several potentiometers for the gas pedal, brake and clutch and handbrake, as well as several switches for the shifters. so what should I learn first ?? I see some people who make the steering wheel have their own application. please tell me, I want to make it myself:flexed_biceps: DIY greetings

Hello, I have a question regarding the use of the timer function xor input for the hall sensor in the BLDC motor, how do I read the first rotor position to start, then I understand that each timer interrupt changes the commutation.

I'd like to porting software from P-NUCLEO-IHM03 (NUCLEO-G431RB + X-NUCLEO-IHM16M1) to NUCLEO-G474RE+ X-NUCLEO-IHM16M1.Are there hardware differences between NUCLEO-G431RB and NUCLEO-G474RE that exclude such software porting?I installed on my PC software Motor Control Workbench 5.4.6 and Motor Profiler 5.4.6Can you any suggestion in that case?Thanks in advance for your help.Best regards,Piotr Olczyk

Please help me out !!I need to get the Configuration for a Brushless Motor for a Drone (Racerstar 2207S).I got all the Motor Data and did the first configuration in the MotorControl Workbench 5.4.6. then Generat the files an opend it in the STM32CubeIDL. after that i did a download to the ESC. Now i got the Connection with the Motor Control Workbench.When I conect the ESC and try to start, the Software shows me direct Over current without starting at all.After that i was not sure if I got the Motor Parameters correct. To check that i tryied to the Motor Profiling with the Motor Profiler 5.4.6. After counting the Pole Pairs again (7), and max Current 32.6A I startet the Profiling. The Tool startet the measurment and the Motor startet spinning. that was realy exiting. but by passing around 80% it stops and showd a fault that the measurment is going to long.When i tryied it again, the bord was getting so hot, with a max of 25Apk that one of de

I noticed that Switched Reluctance motor control is an option in the MC Suite but it is not selectable. Are there plans to support switched reluctance control in the future? Who's working on SR implementation on ST hardware?

and I have an error " communication is closed, the board does not work correctly" . what should I do to solve this problem? I have checked the power supply and I tried to reflash the board but always the same problem. Thank you , Mohamed

The new release 5.Y of the STM32 Motor Control Software Development Kit (X-CUBE-MCDSK) offers the new SW tool “STM32 MC Motor Pilot�? (real data log capabilities thru customizable interface), support AC Induction Motor and new 6-step control for BLDC motors (as FW example) and many other new features in the FW library (Discontinuous PWM, Single shunt phase shift, Overmodulation, Circle limitation V2 (replacing Legacy Circle limitation).The STM32 Motor Control SDK 5.Y is a step in between the current legacy version (v5.4.6 ) and the coming V6.0 (planned for beginning 2022).We use a “Y�? in the naming as FW library is closer to the coming STM32 MC SDK 6.0 while the STM32 Motor Control Workbench, the configurator tool (GUI), is identical with the one present in the STM32 MC SDK4.5.6 (legacy version).

We are using STM32F301 micro along with 5.4.4 motor control SDK. We found that at different speeds we get different power measurments for the same amount of power output of the motor. Is this due to the fact that PQD_CalcElMotorPower() does not use power factor for calculating power? In our user code we are using MPM_GetAvrgElMotorPowerW(pMCT->pMPM) to limit the output power of the motor and this is not working properly because of the accuracy of the power measurement at different speeds of the motor.

For a new motion control application it would be beneficial to control two servo motors (in velocity control mode) with one STM32 MCU. It would require to generate two PWM signals based on Hall sensor feedback from two servos. The two motor velocities are not identical. Do any of you have experience with that configuration? Is it technically feasible? What are possible pitfalls? Thank you!

Hi, first the good news: I have motor control up and working. And communication with the workbench works fine. Having read up on the ST motor control protocol, and watching serial comms with the HHD software device monitor app, I can see that commands are 4 to 6 bytes, and acknowledges about the same. I've extended the protocol (by subclassing MCP_Init), to add a custom command and acknowledge, that are each 10 or so bytes. And I was shocked to find that mostly, it works. Now the bad news, I get error acknowledges indicating 'overrun', when the motor is running. The help on this error is not much help :\ Can anyone shed some light on how to resolve? I have as one does, tried a bunch of things, all either destabilised motor control or didn't help. Very briefly 1) Experimenting with USART1 NVIC prio wrt TIM2. 2) Lowering or raising baud from the present 9600. 3) Inserting an inter-byte delay to the command and/or acknowledge. 4) In Cube, disabling overrun detect, however the ove

I want to use an STM32G4 to control a BLDC motor with three (U-V-W) Hall Sensors (through a TI DRV8323S three-phase integrated gate driver). To be concrete, I am planning on using TIM1 on the STM as the interfacing timer to detect state changes (on U-V-W), and TIM20 to generate the 1x or 3x PWMs necessary to instruct the DRV8323S what to do next. I understand that DMA can be used to trigger TIM20 that a change in phase on the U-V-W channels has been detected by TIM1, bypassing any involvement at all by the Cortex M4 core. This sounds slick. Two questions:1) Is there an accessible tutorial online somewhere with the details of how to set up the code on an STM32 to make such a bridge between timers (through DMA, bypassing the ARM core) for BLDC motor control with Hall sensors? I haven’t found it yet…2) Though I understand it is not ideal, about how much additional latency (and, thus, motor-inefficiency) is added (say, for a typical m

Hi, I'm going to write a parameter tabe into the last page of the flash in my MC Workbench project running on STM32F302R8. I made some tests and seems that programming the flash while the motor is in IDLE state is working fine. If I program the flash while motor il running I get a bad transient in motor drive. I'd like to know if it is safe programming the flash while the motor is stopped or if it's mandatory to reset the MCU after flash programming to avoid any problem or illegal/corrupted state. Thank you in advance Claudio Simeone

I am geeting errors when generating the project for EVSPIN32F0601S3, this concludes with: Completed with Errors.So, when I close the Project Generation, the Workbentch says Generation failed.I have now changed the location where the projects are being saved, but the following error still present:2021-03-15 22:21:05,312 DEBUG [LineInfo_to_exitCode.log_LineInfo] 2021-03-15 22:21:05,311 [ERROR] IPConfigManager:1461 - ERROR: the RefConfig ADC_InternalChannelConfig is not available in your config.xml file.Please advise.

Hi,I am trying to feed my Stm32F4 Discovery with 5v in pins. I have tried to feed it with ESC's BECs , PDB or with voltage regulator and Li-Po battery but I am still facing with problems.The problem is that when I try to make PWM generation in tim4 in all 4 channels, there is no problem. but if I try to use tim3 4 motors works when it is connected with Pc via microUSB, when I feed stm externally just 2 or 3 of them works.I can not understand reason of this problem and how can ı fix it. Now I can use tim4 and be aware of this problem but I wonder the reason of problem and is there any other pins have this issue ?
