摘要 研究工程系统切换优化控制问题,为提高系统的稳定性,解决观测器子系统中存在的可观测和不可观测切换问题,提出了线性切换系统的反馈镇定的设计方案。方案根据对切换系统复杂性的认识的基础上,采用构建各种类型的误差子系统函数以及各种增广子系统函数的形式,求解一个线性矩阵不等式观测器增益矩阵的问题,从而得到了可观测子系统控制律的求解方法。进行仿真的结果说明,控制方法可使观测器子系统达到稳定,证实了方法有效性。 In order to solve the problem of observable and unobservable switching which exists in observing subsystem,the article puts forward the feedback stabilization of linear switched systems design.Based on the understanding of the complexity of switched systems,the program constructs various types of error sub-system functions and a variety of augmented sub-systyem functions to solve the gain matrix of linear matrix inequality observer,and obtains the solving method for control law of observable sub-systems.Simulation example shows that the control method makes observing sub-system stable,which validates the effectiveness of the method.
