Abstract

This paper illustrates various techniques to achieve the best optimization method under the Linear quadratic control strategy that is used for a multiple input multiple output system. The objective of the paper is to find the control criteria using the principle of extended state observer. An advanced optimized iteration method was introduced to select the weighted matrix Q from the control parameters. Another method is simulink response optimization method which also can fulfil the desired output result shown in the paper. Both the variables, the weighted matrix Q and the observer gain La, was modified after applying these optimization methods. The method responses were as per the minimal damping ratio of control logic. Among all these algorithms, the best iterative result was initiated.
