The Identification and Discrete-state-predictive Control for Multi-input-multi-output Time-delay Systems

Abstract

This paper proposes an estimation and control method for multi-input-time-delay systems. It has already been established that the model which estimates a single-input-time-delay system increases its order according to the time-delay steps because the model has to store input as states. Therefore, it is possible to estimate time-delay steps by checking the order of the estimated model. On the other hand, the control method for single-input-time-delay systems is known as state predictive control. This paper extends this concept to multi-input-time-delay systems, proposing an estimation method for multi-input-time-delay systems and state predictive control. The effectiveness of this extended approach is validated by simulations.
