一类鲁棒观测器的存在条件
Conditions for the Existence of One Type of Robust Observers
-
摘要: 本文给出一类鲁棒观测器的存在条件.在此条件下,系统状态的观测误差可以完全不受 系统非线性因素、参数不准确及参数变化的影响.数值实例验证了这一点.Abstract: Necessary and sufficient conditions for the existence of one type of robust observers are proposed and proved in this paper. Under such conditions, it is possible to design a state observer, the estimation error of which is totally unaffected by the nonlinearities, parameter uncertainties and parameter variations of the system to be observed.
