摘　　要：考虑一类参数一致有界、分段Ｌｉｐｓｃｈｉｔｚ连续的线性时变系统的自适应控制问题。当系统参数的间断点个数平均少时，采用一种允许系统参数快速变化的极点配置控制策略。对系统参数部分未知的情形，应用带有投影与正则化的估计器得到稳定的间接自适应控制方案。The adaptive control issue of a class of linear time-varying systems with uniformly bounded but piecewise Lipschitz continuous parameters is considered. A pole-placement control strategy, which allows the system to be with fast varying parameters, is employed, under the condition of the number of discontinuities of the system parameters being small on average. For the case of the system parameters being partially unknown, an indirect adaptive control scheme is developed by combining the controller with an estimator of projection and normalization.
