研究了离散和连续线性切换系统的共同二次Lyapunov函数.对于系统矩阵为分块上三角或分块下三角矩阵的两种情形,给出了一些关于共同二次Lyapunov函数的性质.
The common quadratic Lyapunov functions for a family of discrete or continuous stable linear systems which are called switched systems were studied. If system matrices are block upper triangular matrices or block lower triangular matrices, some results about the common quadratic Lyapunov functions were provided.
