摘要: 针对一类非线性连续系统,利用小波网络逼近原系统的α阶积分逆系统,针对复合后 的伪线性系统提出了基于逆系统方法的内模控制,证明了闭环系统的鲁棒稳定性,分析了系统 性能.仿真结果表明所提的方法控制性能好,精度高,且控制器设计简单.Abstract: Wavelet networks are used to approximate to the a-integral inverse system of a class of nonlinear continuous systems. Then the internal model control based on inverse system method is proposed for the combined pseudo-linear system. Stability and robustness of the closed-loop system are proved, and its performances are analyzed. Simulation results show that the method has better performance, high accuracy and simple design.
