跳跃线性系统是一类具有随机跳变参数的线性系统,其跳变参数根据给定的有限状态马尔科夫链演化,这样的模型可以用来描述出现故障或者在结构上突然发生变化的系统.本文采用随机李雅谱诺夫第二方法研究了具有干扰的离散时间跳跃线性系统的几乎处处稳定性,得到了一类充分条件.并由此条件进一步得出了更易于检测其几乎处处稳定性的充分条件.
A jump linear system is defined as a family of linear systems with randomly jumping parameters governed by a Markov jump process. It is used to model the system subject to failures or changes in structure. The almost sure stability of a discrete-time jump linear system with disturbance is studied by using the stochastic version of Lyapunov second method. A sufficient condition for almost sure stability is derived. Some new simpler tractable sufficient conditions for almost sure stability are obtained from the proposed sufficient conditions.
