In order to make motor drive system had a better man-machine interface function and data processing function of DSP could be realized fully,this paper designed a monitor system about AC speed control.In this system,PC was a host computer and DSP was a substrate machine.MSComm used in serial data communication based on Delphi.The paper designed the host computer procedure,substrate machine program and communication protocol.At last,the host computer realized a credible monitoring to AC motor in direct torque control system.We could change the controller's parameters online and observe the influence in control system during all process.This kind of configuration was convenient for control system developing and debugging in the future.It had powerful and general-purpose functions,and friendly user interface.
