Stability Analysis of Uncertain Discrete Time-Delay Control Systems

摘要

Based on Lyapunov stability theory, a less conservative sufficient conditions for the stabilities of uncertain discrete delay- independent and delay-dependent control systems are obtained by using the linear matrix inequality (LMI) approach. Judgement of the stability of time-delay systems is transformed to judgement of the feasible solution of an LMI, and hence is solved by use of MATLAB. Numerical simulations verify the validity of the proposed method.
