Identification and Control of MIMO Systems with State Time Delay (Short Communication)

Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is based on the stochastic phenomena which are capable of identifying each state variable independent of other variables, a control strategy for controlling such systems; and furthermore confirming the stability criteria. The results demonstrate the effectiveness of the proposed control strategy which has the advantage of confirming the stability, simple implementation and analysis.
