| Abstract | ||
| The design of multi-input multi-output (MIMO) industrial control systems, by use of the modern control theory, usually leads to considerable difficulties as a direct consequence of the following points: the mathematical models are usually of high order and the state feedback schemes are of complicated nature. The present research deals with the problem of simultanious decoupling and control based on the diagonal dominancy over certain frequency range and the stabilization of the inverse Nyquist array (INA) plots at an optimum point. An approximate design technique is proposed for certain class of (MIMO) systems. The effect of emergency outage of one of the controllers is studied. The results have been checked by simulating two-input two-output system on the analog computer. | ||
