线性时滞切换控制系统的二次稳定:Krasovsikii方法
Krasovskii approach to quadratic stabilization of linear time-delay switched control systems
【摘要】 研究线性时滞切换控制系统的稳定性问题,利用卡拉索夫斯基(Krasovsikii)定理和凸组合技术,构造了新的切换系统的公共Lyapunov函数和切换信号,给出了新的二次稳定的充要条件.最后给出了仿真算例,验证了它的有效性和正确性.
【Abstract】 In this paper,the problem of quadratic stabilization of the linear time-delay switch control systems is investigated.According to Krasovsikii theorem,a new common Lyapunov function of switching systems and switching signal is constructed.Then several new necessary and sufficient conditions are given by convex combination.Finally,a simulation of example,it proves their effectiveness and correctness.
