freescale MCU,S12G128的ADC模块与PWM模块的使用，通过电位器模拟电压输入，控制PWM的占空比输出，可以控制LED灯、电机驱动等任务。(freescale MCU S12G128 ADC module and PWM module, an analog signal input control the PWM duty)

文以永磁同步电机为对象，采用矢量控制方案，首先我们研究了基于PI 的控制算法，在仿真基础上指出了PI 算法存在的一些不足。 在此基础上我们研究了基于扩张状态观测器（ESO）前馈补偿和线性比例反馈控制的永磁同步电机速度环控制算法， (Taking PMSM as the controlled plant, this paper studies the control system based on vector control, first, the servo control scheme based on PI control law is studied. Some limitations of PI based control scheme are pointed out. )
