Based on the analysis of interactions between different systems in the network, it is proved that, for a class of complicated linear switched system network, an equivalent model of ordinary linear switched system exists and the corresponding model is given.(4) Block simulation model of linear switched system is established in Matlab/Simulink environment and, moreover, a linear switched system simulation tool with the function of model automatic generation is developed. With the aid of this simulation tool, influence caused by switching sets on stability characteristic of linear switched system is investigated.
