Time Delay MIMO System Control Using Dominant Gain Compensator

A new method is presented in this paper to improve the performance of time delay Multiple-Input Multiple-Output systems. The method uses a specific compensator for each of the control loops by which the non-minimum phase characteristic of the open loop functiondchanges to minimum phase. When using the proposed added compensator for robustness of the system it is sufficient that compensater becomes dominant gain with respect to the upper norm of the uncertainty of the process. The proposed method is applicable easily in a convetional feedback control loop.
