Abstract :
In this paper, the principle of energy-saving by regulating the stator voltage of asynchronous motors and the relationships between the slip and the efficiency/power factor are analyzed, based on which the control principles of optimal slip rotating speed with maximum efficiency, minimum current, minimum input power and maximum power factor are investigated in detail, and than the PID controller that the parameter turned by BP neural network is designed, the result of experiment revealing that the essential of these control.
