摘要
针对交流伺服系统转动惯量、负载力矩变化大的特点,提出了联合控制策略。设计自适应预测控制器和单神经元PID控制器,自适应预测控制可实现较好的跟踪特性和鲁棒性,单神经元PID控制可对传统PID控制器的比例、积分、微分系数进行实时调整,抑制了参数摄动和负载扰动。仿真结果表明,所设计的联合控制器能够保证系统的静、动态性能。
Aiming at w ide variations in loads and moments of inertia of AC servo system,joint control strategy w as developed. The adaptive prediction control and the single neuron PID controller are designed,adaptive prediction controller has tracking performance and good robustness,single neuron PID control can adjust proportional,integral and derivative coefficients of the traditional PID control in real time,then can inhibit parameter perturbation and load disturbance. Simulation results show that the joint control strategy can guarantee the static and dynamic performance of the system.
