Abstract
In this paper, Luus-Jaakola (LJ) optimization based PID controllers are proposed for level control of double tank system. Two controllers namely PI and PID are designed for such level control. The integral-square-error (ISE) of unit step response is considered as design criterion. The ISE constructed requires fixed number of alpha and beta parameters. LJ algorithm is used for minimizing the ISE. The results obtained are compared for three controllers. The proposed scheme shows excellent results in terms of time domain specifications.
