THE APPLICATION OF FUZZY CONTROL FOR THE LIGHT-LOAD VOLTAGE REDUCING AND POWER-SAVING IN THREE PHASE ASYNCHRONOUS MOTOR

Considering both traditional PID control and fuzzy feedforward compensation, this paper proposes a compound approach of fuzzy control+fuzzy feedforward compensation. This approach solves the problem of optimal control while the dynamic plants are nonlinear, time varying and uncertain. The approach found application in light load, voltage reducing and power-saving apparatus controlled by MCS-51 chip microprocessors. The result is satisfactory.
