PIC18F4431实现交流感应电机的控制。程序中讨论了几种方案，开环V/F，V/F加上电流反馈，然后再加上速度反馈。-PIC18F4431 AC induction motor control. Procedures discussed several options, the open-loop V / F, V / F with current feedback, and then coupled with the speed of feedback.

使用PWM信号控制电机转动，根据伺服编码反馈信号确定电机位置。-Using the PWM signal to control the motor rotation, determined according to the servo motor position feedback signal coding.
