Abstract
There are a lot of multi-inputs multi-outputs (MIMO) systems in the chemical plants of the manufacturing, and they have the multiple time delays which are different length in each their inputs and outputs pair. This paper proposes a new technique for the MIMO system with the multiple time delays. Generalized minimum variance control was used for the control design method. The following states of time delays are held in one sampling interval by selecting sampling period. The states between the sampling period can be expressed by using the modified z transform. Thus, the discrete-time model of controlled object is obtained, and MIMO for GMVC is designed by using this model.
