Designing a lower controller makes the real time implementation easier in most of the process industries and peculiar systems. The designed controller needs to maintain the robust stability, robust performance, time domain specifications with respect to Gain and Phase Margin to make it more usable and realizable. The order of the post modern controller (H∞) makes the implementation difficult in the real time systems. Genetic Algorithm can be used to select the initial parameter of the lower order controller design. Before starting the initial parameter search, the lower order controller structure needs to be defined with the unknown parameters. In order to reduce the search time of the initial unknown parameters, we can compare the magnitude response of sensitivity and complementary sensitivity functions of the higher order controller and the proposed lower order controller design.
