Control of Quadruple System using Modified Model Reference Adaptive Control

Abstract: The Quadruple System is a typical control system with nonlinear, coupling and time delay characteristics which can be used to test the applications of different control algorithms on complex systems. The aim of the process is to keep the liquid level in the tanks at the desired values. Here, Modified Model Reference Adaptive Control is proposed and is applied to the four tank system to test its performance. Time domain parameters like Settling time, Rise time and Mean Square Error are used for evaluating the performance of the controllers. The response of the controller is verified and is compared with other control algorithms through simulation. The performance of the closed loop system is simulated using LabVIEW software. The method used here is validated using the simulated results.
