| 摘 要： | 针对离散时间不确定混沌系统的同步控制问题,提出一种基于参数依赖动态输出反馈鲁棒模型预测控制算法.首先,采用主动控制策略,将具有噪声扰动的主从混沌系统同步问题转化为鲁棒稳定性问题;然后,采用参数依赖动态输出控制器和二次有界概念,在保证闭环系统鲁棒稳定性的同时,降低算法的保守性;最后,通过附加约束条件,能够显式处理混沌系统同步中的输入约束.仿真结果表明了所提出算法的有效性.

| Abstract: | A kind of parameter-dependent dynamic output feedback robust model predictive control algorithm is proposed to synchronize two identical discrete-time chaotic systems with parameteric uncertainties and energy-bounded disturbances. Firstly, the active control strategy is employed to reformulate the chaos synchronization with master-slave structure into the standard robust stabilization problem. Then, both concepts of quadratic boundedness and parameter-dependent dynamic output controller are introduced to stabilize the augmented closed-loop system for less conservativeness. By adding additional constraint conditions, the physical input constraints are handled explicitly. Simulation results show the effectiveness of the proposed algorithm. |
