摘要
针对可能存在状态时滞且状态不可观的未知系统,本文研究了基于事件驱动观测器的鲁棒控制问题.与控制器被周期性更新的正常采样控制系统不同,在事件驱动系统中,只有在事件发生时才会更新控制器,并且事件的发生通常由一些误差信号是否满足某种设定好的条件来判断.对于带有参数摄动的未知系统,提出了控制器增益矩阵与观测器增益矩阵的求解方法.结果表明,在事件驱动下,针对参数摄动系统提出的控制方法依旧能够镇定系统.最终,通过一个仿真案例验证了本文方法的可行性和有效性.
This paper investigates the robust control problem of unknown systems based on event driven observers.Unlike normal sampling control systems where the controller is periodically updated,in event driven systems,the controller is only updated when an event occurs,and the occurrence of an event is usually determined by whether some error signals meet certain predetermined conditions.For unknown systems with parameter perturbations,a method for solving the controller gain matrix and observer gain matrix is proposed.The results indicate that under event driven conditions,the proposed control method for parameter perturbed systems can still stabilize the system.Finally,the feasibility and effectiveness of the method proposed in this paper were validated through a simulation case.
