High-speed High-precision Digital Servo System Is Developed

In this paper, a high performance digital servo-system based on an industrial control computer is studied. In order to connect to peripheral equipment, a periphery interface card and an ISA bus card is designed. Furthermore, after designing the drivers under Windows98 for the ISA bus card, the method to control in real time via VxD under Windows98 is expounded in detail.We are living in an information times, internet has entered all our aspects. In order to achieve the remote control of the control systems, the paper makes a good try, and successfully realize the remote control of the servo-system. The control style is browse/server. The servo-system will be well controlled in distance in virtue of general browser, and the special software is no need yet.Finally, a'kind of intelligent PID is given and put into use in the servo-system. Experiment results show that some shortcomings of routine PID can be well conquered and good perfomance can be achieved.
