Summary:A new control technique based on a neural network, is proposed here for control of AC servo motors. The PID control is widely used in servo systems as it has simple structure, safety and reliability. However, it has certain problems in a complex system, resulting in imperfect action in the presence of uncertain parameters. To solve these problems, a new hybrid control algorithm of the PID controller is proposed, which could prove the adequacy of the proposed control algorithm through simulation and experiments after driving the AC servo motor system using neural network PID controller.
