摘要
应用驻留时间方法和平均驻留时间方法研究了一类由脉冲作用的离散广义切换线性系统的稳定性,给出了系统指数稳定的充分条件,讨论了当平均驻留时间足够大且重设律是允许的,那么系统是全局指数稳定的,利用广义系统受限的等价性质具体给出重设律的设计方法.数值算例和仿真方法说明了本方法的有效性.
The stability of discrete-time singular switched linear systems with impulsive effects is studied by using dwell time and average dwell time approaches. Sufficient conditions for exponential stability is presented. It is shown that if average dwell time is chosen to be sufficiently large and the reset law is admissible,and exponential stability is guaranteed. The admissible reset law is developed using the restricted equivalent property of singular systems. The validity of the algorithm is illustrated in a numerical example.
