中文摘要： 切换型混杂动态系统（Hybrid Dynamic System, HDS）简称切换系统，是现代计算机应用技术特别是数字控制技术渗透到连续变量动态控制系统中的产物，因此切换系统的鲁棒控制研究近年来引起国际国内学术与工程界的关注。实际工程中普遍存在大量不确定性和各式各样切换规则，而现有的切换系统控制研究限于鲁棒H无穷控制器综合方法，处理和解决实际问题的能力有限。本项目通过滑模变结构控制理论的思路和方法来进行不确定线性切换系统的鲁棒控制研究，提出切换系统鲁棒积分滑模控制器综合的新观念，首先解决滑模面设计与整个系统鲁棒稳定性的判别问题，并提出在各种滑模递阶到达模式下系统鲁棒稳定的充分条件。在此条件下，研究一类不确定线性切换系统鲁棒积分滑模的可达性问题，完成整个系统积分滑模控制器的分析与综合，并应用到矿井电力电子装置与电机调速系统的研制中去。项目具有重要的理论意义，也有广泛的应用价值。

英文摘要： The switching type hybrid dynamic systems(HDS) referred to as switching system has resulted from the penetration of modern computer application technology, especially digital control technology to control of continuous system. Correspondingly, research work of robust control for switching system in recent years attracted attentions of the international and domestic academic and engineering. Moreover, abundant uncertainty and wide range of switching rules are prevalent in the actual applications. However, the existing switching system control methods limited in robust H infinity control have restricted ability of handling and solving practical problems. In this project, robust control research of uncertain switching systems by the ideas and methods of the sliding mode variable structure control theory is evolved, in which the new concept of robust integral sliding mode controller synthesis for switching system is proposed. Firstly, problem of the sliding surface design and the stability validation of the overall system are to be resolved. Meanwhile, several sufficient conditions of system robust stability under several hierarchical reaching of the system slidng mode are to be presented. After that, the reachability problem of robust integral sliding mode for a class of linear switching system is researched. Hence
