Quantized Stabilization of Continuous-Time Switched Systems With Delay and Disturbance
针对受未知扰动、数据量化和时变时滞影响的连续时间切换系统,提出了一种基于虚拟系统的通信与控制策略,利用扰动界估计和Lyapunov函数保证闭环系统的指数衰减和实际稳定性。
This article addresses the problem of stabilizing a continuous-time switched system affected by a completely unknown disturbance, data quantization, and time-varying delay. In the sense of combined dwell-time and average dwell-time, it is assumed that the switching is slow enough. Suppose that the bound of delay is known but the one of disturbance is unknown. An estimation for the bound of disturbance is used to counteract the unknown disturbance. By extending the approach of the delay-free case, a communication and control strategy is developed by introducing a virtual system. On this basis, the exponential decay and practical stability of the closed-loop system are guaranteed by using a Lyapunov function. Two examples are illustrated to show the usefulness of the proposed framework for stability analysis of some classes of switched systems.
