摘　　要：针对状态矩阵具有复特征值的稳定二维连续线性系统,提出了一种基于采样数据的混沌反控制方法。该方法以给定的采样周期对连续系统进行采样,由采样数据的正弦函数构造反馈控制器,使连续系统产生混沌。在每个采样周期内保持控制项不变。数值仿真结果证实了该方法的有效性。作为一种数字控制技术,该方法设计的控制律较连续控制律更易于工程实现。Chaotic an anticontrol method for a class of stable two-dimensional continuous time linear systems with state matrix having complex eigenvalues is proposed by using sampled data. The system state variables are sampled at a given sampled rate and a sine function of the sampled data is used to construct a discrete time state feedback controller making the continuous time linear system chaotic. During each sampling period, the feedback control input keeps unchanged. The simulation results verify the effectiveness of the proposed method. As a digital control technique, the control law designed is more easily implementable than a continuous-time control law in engineering applications.
