摘　　要：对具有未知参数的 Lipschitz非线性系统自适应观测器设计问题进行了讨论 .首先 ,在一定的条件假设下 ,讨论了可同时辨识出系统常量参数的全维自适应观测器 .然后 ,在同样的条件下 ,基于一坐标变换的方法 ,提出了一种降维自适应观测器设计方法 .由此得出结论 :具有常未知参数的 Lipschitz非线性系统在同样的条件假设下 ,既可进行全维自适应观测器设计 。The problems of adaptive observer's design for Lipschitz nonlinear systems with unknown parameter were dealt with. First, the full-order adaptive observer which can identify the unknown parameter was discussed under some assumptions. Then, under the same assumptions, a way to design the reduced-order adaptive observers was developed based on a coordinate transformation. Finally, it was concluded that not only the full-order adaptive observer but also the reduced-order adaptive observer can be constructed under the identical assumptions.
