Performance and stability analysis of an adaptive controller for a non interacting system

This paper deals with continuous time adaptive control of a nonlinear two tank non-interacting system. To control the level in the tank, controllers with two degrees of freedom are designed and implemented. The controllers designed are based on gradient approach and the stability approach, resulting the closed loop control system to have asymptotic tracking. Both the controllers are based on the minimization of mean square error. Even though these controls are non-identifier type, to have apriori knowledge and for simulation purpose the nonlinear system is modeled as SOP using real time data. The performances of the controllers are tested in Simulation.
