摘要: 把输入-状态线性化的方法用于混沌控制。仿真分析了一种非线性反馈系统的动力学行为,用相轨迹及功率谱法证实了在某些参数和初始条件下该系统会产生混沌行为,用输入--状态线性化的方法设计了反馈控制器,使混沌系统实现了稳化和跟踪,仿真结果证明了该方法的有效性。

Abstract: Input-state linearization method is used for controlling chaos. The dynamic behaviors of a class of nonlinear feedback system are analyzed through simulation. It's proved by phase-locus and power-spectrum method that this system can produce chaotic behavior under some parameters and initial conditions. A feedback controller is designed with inputs-state linearization method, which realizes the stabilization and tracking in chaotic system. Simulation results are presented show the effectiveness of the method.
