摘　　要：研究了一类不确定线性切换系统的二次鲁棒镇定问题。这类系统不仅包含不确定项,而且在输入通道中也包含不确定性。给出了这种不确定线性切换系统二次鲁棒镇定的充分条件。当某类矩阵是负定时在任意的切换策略下,可以保证系统的二次鲁棒镇定。The quadratic robust stabilization problem for a class of switched linear systems with uncertainties is studied. The systems not only contain uncertainties, but also experience uncertainties in the input channels. The sufficient conditions for quadratic robust stabilization of the switched systems with uncertainties are given. When all of certain family matrixes are negative definite, quadratic robust stabilization under arbitrary switching laws is obtained.
