| 摘 要： | 采用Lypunov方法讨论了一类具有未知参数的Lipschitz非线性系统的状态观测器设计问题, 给出了观测器的结构形式和参数估计的自适应律.并以线性矩阵不等式组的形式给出了观测器渐近稳定的充分条件.合理地选取了增益矩阵,消除了增益矩阵选择不当所带来的保守性和盲目性.改善了有关文献的结果.

| Abstract: | State observer design for a class of Lipschitz nonlinear systems with uncertain parameters is discussed,using Lyapunov method.The structure form of the observer and the adaptive law of uncertain parameters was given.The sufficient conditions ensuring the asymptotic stability of the observer were given in the form of LMIs.Gain matrix has been chosen reasonably,which curbs the blindness and the reservation led by unreasonable decision.Results in relative papers are improved. |
