摘　　要：分析了一类带有不确定量的Lipschitz非线性时滞系统的稳定性和观测器设计.关注的问题是设计一全维观测器以确保误差系统二次稳定.通过利用矩阵分解和解线性矩阵不等式,根据一些自由参数,希望设计的观测器显式表达式被导出.Concerned with the stability analysis and the observer design for Lipschitz nonlinear delay systems with uncertainties. The problem concerned is to design a full-order observer to guarantee quadratic stability of the error. By using the matrix decomposition and solving the linear matrix inequality, an explicit expression of the desired observer is derived in the light of some free parameters.
