Abstract

To improve the transient performance of servo systems and satisfy the high-precision processing requirements of industrial production lines

a fuzzy adaptive deep reinforcement learning algorithm is proposed to optimize the control performance of permanent magnet synchronous motor servo system. According to the rapidity and stability requirements of transient response

the reward function and Actor-Critic networks are constructed

the transient optimization link for servo controller is introduced

and the learning rate fuzzy controller for real-time computing requirements is designed. A servo system Simulink simulation model is established and fitted in with the actual servo system

the optimized parameters are obtained via transient performance optimization simulation and then applied to a Siemens 840D computerized numerical control system. The verification of simulation calculation by system experiment shows that the proposed method of transient performance optimization shortens the servo system adjustment time by more than 10%

significantly heightens the system transient response rate without introducing an obvious overshoot. This method has strong versatility to provide a new way for the intelligent control optimization of the servo system.
