COMPARATIVE ANALYSIS OF ROBUST CONTROL AND CONVENTIONAL CONTROL FOR A NON-LINEAR PROCESS

Senthilkumar K

Abstract: The level tank control of a coupled tank system is relatively crucial when compared to the conventional control scheme. Due to continuous variation in the plant dynamics, controlling is complex one and hence they were approximated as piecewise linearized systems. The various combination of the conventional controller was implemented to maintain the level at particular height. The robust PID is used to achieve the required setpoint. Mathematical model of coupled tank system is computed using material balanced equation approach. The performance of the controllers was compared for the analysis purposes
