Neural Network PID Controller Based AC Variable Speed Drive System

In order to overcome the limitation of PID control and neural network control in the AC variable speed regulating system, this paper proposes a neural network based PID controller to achieve variable frequency speed control, in which the advantages of neural network technique and PID control are integrated. It is shown from simulation results that the proposed method can make the controlled system have better stability, robustness and anti interference performance, and can also improve the dynamic performance of the controlled system.
