【摘要】 考虑含有未知输入的时滞Lipschitz非线性系统观测器设计问题．首先提出针对线性时滞系统的不含内时滞项的观测器系统化设计方法,给出观测器存在的充分必要条件;然后对时滞Lipschitz非线性系统利用代数Riccati方程的解条件设计出一种鲁棒观测器,并给出渐近稳定观测器存在条件．更多还原

【Abstract】 It presents the observer design for a class of delay-time Lipschitz nonlinear systems with unknown inputs. The objectives are two folds. Firstly, a simple and systematic design method of observers without internal delays for the linear time-delay system is studied, necessary and sufficient conditions for the existence of these observers are given. Then a robust observer using the solution of an Algebraic Riccati Equation for the class of Lipschitz nonlinear systems is proposed. The existence conditions of these asymptotically stable observers are given and proved.更多还原
