New Aspects in Reduction of Continuous Time MIMO Interval Systems

Improved Simplified (ISRAM) Routh approximation method is tendered for the decrease of orders of linear interval systems of high order Multi input (MIMO) Multi output interval systems. The proposed method requires only one interval table needs to be designed to produce the reduced-order models. ISRAM for MIMO system model reduction always driven by impulse energy estimation to get around the shortcomings and restrictions of the current approaches. The suggested method always retains the entire response energy of the original continuous time interval systems. The stable starting system's lower order models of high order intervals acquired by using the suggested approach is also satisfying the Kharitonov's stability conditions. Initially take a numerical example 4th order system is used on ISRAM and compared to simplified Routh approximation method (SRAM) has shown by the results. The suggested approach is logarithmically good and in any case generate models of stable reduced orders for a high-order starting system that is stable, models of reduced order those are stable.
