摘　　要：针对离散时间LIPSCHITZ非线性系统的观测器设计问题,依据离散时间系统的LYAPUNOV稳定性理论,研究了保证观测误差渐近稳定的充分条件,并依据该条件应用线性矩阵不等式方法,得到了观测器增益矩阵的设计方法。所得方法计算简便,并通过算例说明该方法的应用。For observer design problem of Lipschitz nonlinear systems in discrete time domain, sufficient condition guaranteeing the asymptotic stability of observer errors is investigated based on Lyapunov stability theory. Based on the given cindition, observer gain matrix design algorithm is derived by using linear matrix inequality technique. The obtained algorthm is simple in computation. An example is given to demonstrate the proposed method.
