基于滑模变结构控制,研究了不确定非线性系统模型到达混沌反控制,保证经有限时间,使受控不确定非线性系统达到与混沌参考系统数学模型完全一致,并就到达的快速性,鲁棒性进行了讨论,最后以Lorenz混沌系统为混沌参考模型的情况进行了仿真,仿真结果表明所给方法是有效的. Based on the sliding mode variable structure control, the chaotic anti-control of the uncertain nonlinear system model arrival is studied. It guarantees that the controllable uncertain nonlinear system is completely consistent with the mathematical model of the chaotic reference system through a finite time, and the rapidity of arrival, The robustness is discussed. Finally, the Lorenz chaotic system is used as the chaotic reference model. The simulation results show that the proposed method is effective.
