对非线性控制系统,采用变结构控制方法,对参数变化的连续混沌系统,提出了几种控制混沌同步的方法,通过对参数误差的估计,利用滑动模实现同步.对部分参数为常数,部分参数变化的混沌系统,用输入输出解耦线性化后的不变流形与滑动模相结合的方法.具体对Lorenz系统进行研究,并给出数值模拟。
For nonlinear system control, based on variable structure control approach, several control strategies of variable parameter chaotic dynamical synchronization are proposed. The synchronization is obtained by the evaluation of the errors and sliding mode. For the system with partly constant parameter and partly variable parameter, we can use the method via an invariant manifold with sliding mode after the system with input - output linearization method. Particularly the Lorenz system is discussed as example and the simulations are given.
