Robust sliding-mode control for a class of uncertain switched systems with time-delay
不确定时滞切换系统的鲁棒滑模控制

The sliding-mode control problem is studied for a class of time-delayed switched systems with mismatched uncertainties and nonlinear disturbances. The delay-dependent sliding surface is designed for each subsystem by using the dwell-time approach. The sufficient condition is deduced under which the switched system composed by sliding-mode dynamic equations is robustly asymptotically stable. Furthermore, a sliding-mode controller is designed which ensure the reachability of the sliding surface; thus the sliding-mode dynamics is resulted. A numerical example illustrates the effectiveness of the proposed design method.
