摘要
用滚动时域H∞跟踪控制方法对一类连续时间混沌系统的控制与同步进行研究。在采样点将受控系统关于目标系统线性化展开得到误差模型,然后设计H∞跟踪控制器。在每个采样时刻,通过在线调节参数和重复求解LMI优化问题,获得最新的控制动作,使闭环系统能实时协调控制性能(跟随性能和干扰抑制性能)和控制约束,并充分利用有限的控制能力提高跟踪性能。
This paper is focused on the tracking control and synchronization of chaotic nonlinear dynamic systems by using the moving horizon H∞ tracking control scheme. The goal system a- round controlled system to form an error system model is linearized firstly, and then the H∞ tracking control law at each sampling time is designed. In order to obtain actual control, The pa- rameters are adjusted suitably and solve the LMI optimization problem on -line at next sampling time is solved. The closed - loop system is able to manage the trade - off between requiring high performance (tracking and disturbance rejection) and satisfying control constraints, and hence make the most of the limited control to achieve good performance.
