Approach of reducing-order and the analysis of stability for switched para-symmetry composite systems
切换拟对称组合系统的降阶方法及稳定性分析

Using the structural features of the switched para-symmetry composite systems,an approach of order reduction for this switched system is given in this paper.From the reduced system,it is very convenient to study the stability of original switched system,including: a) the switched system is quadratically stable under arbitrary switching laws,b) the switched system is quadratically stable under the designed switching law.Finally,results in this paper are validated by simulation.These results are of the significance in both theory and practice to some pragmatic problems such as the large-scale power system,the armada convoy system,the lift system by helicopters and the large-scale animal system.
