Time-Delay Analysis for Active Controlled Structure System

Abstract:

In this paper, a new stability criterion of time-delay analysis is established for active controlled structure system. Based on an improved upper bound for the inner product of two vectors, the maximal value of time delay can be obtained by using LMI control toolbox of Matlab. According to the new method, the maximal delay varying with parameters of controlled structure system is discussed for SDOF system. The criterion is applicable to the theoretical analysis for the delay-dependent stability of SDOF vibrating system. The longer the delay is the worse the efficiency of control strategy. But the system is still asymptotically stable so long as the time-delay lies in the interval of permitted time delay.
