摘要
针对非线性内模控制结构 ,给出了小波网络逼近系统正、逆模型的充分条件和实现方法。在内模控制结构中引入 PID补偿控制 ,改进了内模控制器的性能。仿真结果表明 ,小波网络用于非线性内模控制是有效的 ,内模 + PID控制较单一内模控制具有更快速和平稳的跟踪性能。
The sufficient condition for system model and its inversion approximated by wavelet networks were presented. The nonlinear system internal model control (IMC) scheme was realized, based on wavelet network. A PID controller was added to improve the IMC controller. The simulation results demonstrate that the wavelet network is effective to be used in IMC controller. The IMC+PID controller has the faster and smoother tracking performance than IMC controller.
