摘　　要：考虑一类单输入线性切换系统的可镇定性问题,利用变结构控制对系统进行降维.通过对系统滑动模态的研究,得出了系统一致可镇定的充分条件和系统存在容许镇定策略的充分条件.给出了具体的容许镇定策略集合,并对二阶切换系统给出了详细的容许镇定策略.仿真实例验证了所提出结论的有效性.The stabilizability problem of a class of single-input switched linear systems is considered. The dimension of the system is reduced with the variable structure control. The sufficient conditions of the uniform stabilization and the existence of the admissible stabilizing strategies of systems are obtained through the study of the sliding mode of the reduced systems. And the detailed admissible stabilizing strategy sets are proposed. The completely admissible stabilizing strategies for second order switched systems are given. Numerical simulations show the effectiveness of the proposed method.
