AC Servo Motor Motion Controller Based on WDM

This article discusses the ISA servo control card under Win2000 environment work process, the WDM device driver’s principle, the structure and running process. It researches the WDM device driver design and exploitation by taking the ISA bus as the example. Servo control program is written and PID controller is designed, the parameters are adjusted on-line. Experimental results of AC servo motor show that writing the device driver can realize high-precision timing and controll the position of high-precision servo electromotor.
