摘　　要：利用多Lyapunov函数方法,本文研究了一类切换线性系统的状态跟踪无扰切换控制问题.首先,刻画了控制信号在切换时刻处的抖振抑制水平.其次,通过控制器与切换律的同时设计,实现了系统的状态跟踪和控制信号抖振抑制.最后,将所提出的状态跟踪无扰切换控制策略应用于一个涡扇航空发动机模型的控制设计上,说明了所提出方法的有效性.This paper focuses on the state tracking bumpless transfer control problem for a category of switched linear systems by a multiple Lyapunov functions scheme.First,a description on the restrain level of the control bumps at switching instants is proposed.Then,by co-design of a switching law and a series of controllers,the state tracking and bumpless transfer control are realized.Finally,the effectiveness of the developed control strategy is shown by applying the proposed state tracking bumpless transfer control approach to a turbofan aero-engine model.
