Research of Complex Fuzzy Control on-off Magnetism Team Motor Speed-Adjusting System

Usually on-off magnetism team motor speed-adjustinga adopts traditional linear control algorithm (such as PID). In modern control system, it is nonlinear, multivariable, multi-coupling, high-dimension and the object is time-varying, uncertain and difficult to describe by math model because of the complex control object. The traditional algorithm is difficult to meet the need of on-off magnetism team motor speed-adjusting. The paper takes the fuzzy control technique into on-off magnetism team motor speed-adjusting system, designs a complex fuzzy control motor speed-adjusting system. The system composed to be a real-time data collection and control system by computer, A/D, D/A and sensor. It adopts on-off magnetism team motor (rating power 11kw, rating rotate speed 1500rpm), analog load (0~10kw) to take a platform-frame experiment and make the system precision and dynamic performance achieve the need. Actually it is turn out to be feasible to use motor speed-adjusting, at the same time, have a good effect. After we take it, the control precision has been improved and had a good effect on improving the system quality.
