Abstract :
Partially decentralized control for a quadruple tank process is studied in this paper. A quadratic tank is a multivariable, nonlinear process with time delay and strong coupling. Considering that a decentralized control will not achieve the desired performance, and that a centralized multivariable control is usually complex and difficult to implement, this paper designs a partially decentralized controller for a quadratic tank. Partially decentralized control is a structure that lies between the fully decentralized control and the centralized control. Design and simulation results show that the proposed partially decentralized controller can achieve comparable performance as the centralized one, but has a simpler structure and is easier to implement and tune.
