Design of Compensator of Approximation of Large Time Delay Systems via Reduced Order Model

The present paper deals with a approximating method for large time ? delays of multi-input multi-output (MIMO) dynamical systems. Time delay terms of the state space equations are described by delay matrix in the complex domain. A mixed model reduction method of matrix Pade-type-Routh model for the multivariable linear systems was presented. Matrix Pade-type Routh model approximation can largely reduce the instability and the overshoot, so the fast response property is improved. Simulation results of the proposed method are presented to illustrate the correctness and effectively.
