开始说FOC之前，我们先来弄清楚电机是怎么动起来的，电机的q轴、d轴是什么，FOC存在的意义是什么。

参考simpleFOC代码，在stm32G431上实现了20kHz的FOC电流环。为了降低驱动器成本，将主控由G431改为F030，目前所有代码均为浮点计算，实现了4kHz的电流环（FOC单周期时间成本约230us），控制效果一般，可作为初步参考。后续需要改为定点计算，提高电流环频率以优化控制效果。。程序架构采用了ST电机库的方案，在ADC采样完成中断里执行FOC程序。驱动方式为3个EN端加TIM1三通道PWM输出，TIM3采集编码器AB相输入，3通道ADC扫描采样三相电桥低边通道采样电阻电压。TIM1为中心对齐模式1，PWM模式2，RCR设为1（每两次溢出触发一次中断，即在下溢时触发ADC采样）。上电后电机开环运行，校对Z相（外部上升沿中断）信号，确定编码器初始偏移量，调试时将变量start_run修改为1以开始执行闭环程序。电流环程序放在ADC采样完成回调函数里面，首先获取编码器计数值并计算电角度，然后获取电流采样值并经过clarke变换和park变换得到qd电流，再经低通滤波和PID计算后得到qd电压控制量，然后逆park变换并计算SVPWM占空，最后经TIM1输出三相占空。

STM32电机控制开发包完全版V5.5.1-5.Y.1，2021年5月3日更新。 STM32 Motor Control Software Development Kit (MCSDK) - FULL source code Main Changes Version 5.Y.1 of the Motor Control Software Development Kit (X-CUBE-MCDSK) is a bug fix release of version 5.Y.0. It fixes the following issues: Some Motor Control examples delivered with MCSDK 5.Y.0 would not configure DMA channels properly to work with the new Motor Control and thus with the Motor Pilot. Also, the baudrate of the UART port configured by examples is set to 1,8 Mbps, the same as ST Motor Pilot's default. ACIM motor based examples do not build on 5.Y.0. They build well on 5.Y.1. The descriptions of EVSPIN32F0x inverter boards delivered with the Workbench had wrong DC & AC voltage supply ranges. These have been corrected as follows: Inverter Wrong AC supply range Corrected AC supply range DC supply range EVSPIN32F02Q1S1, EVSPIN32F0251S1 20 - 120 Vac 15 - 120 Vac 20 - 170 Vdc EVSPIN32F06Q1S1, EVSPIN32F0601S1 50 - 280 Vac 35 - 280 Vac 50 - 400 Vdc EVSPIN32F06Q2S1, EVSPIN32F0602S1 50 - 280 Vac 35 - 280 Vac 50 - 400 Vdc EVSPIN32F06Q1S3, EVSPIN32F0601S3 50 - 280 Vac 35 - 280 Vac 50 - 400 Vdc Six-Step High Voltage examples based on the EVSPIN32F0251S1 inverter board were mistakenly not included into 5.Y.0 version. They are in 5.Y.1. The Pilot would fail to update registers values from the embedded application in some situations. In such a case, information like the motor rotation speed, status and error information would not display. Fixed issues with the DAC output feature. Added many signals to the Datalog and the DAC output features. Among them, the observers, encoder and Hall sensors angles. Running the motor in the negative direction on STM32F0 based designs with 1 shunt and Hall sensor configuration may trigger an overcurrent error. Fixed an issue found on ESC G4 and F3 inverter boards with Motor Control Protocol v2. Contents Components Version License Terms Release Note Utilities/PC_Software/STMotorProfiler 1.3.2
