Issues in Time Delay Modelling

Abstract This paper addresses the problem of time delay modelling using rational approximations. Two classes of models are discussed based on all-pole and all-pass transfer functions. A detailed analysis is carried out comparing the respective merits of these approximate models. The estimation of the parameters in these models is investigated and the associated control design problem using rational models for the delay is studied. Simulation results are presented which support the theoretical analysis
