MULTIVARIABLE LABORATORY PROCESS WITH AN ADJUSTABLE ZERO: QUADRUPLE-TANK PROCESS

      This project is designed based on Quadruple-Tank Process. A novel multivariable laboratory process that consists of four interconnected water tanks is presented. The linearized dynamics of the system have a multivariable zero that is possible to move along the real axis by changing a valve. The zero can be placed in both the left and the right half-plane. In this way, the quadruple-tank process is ideal for illustrating many concepts in multivariable control, particularly performance limitations due to multivariable right half-plane zeros. The location and the direction of the zero have an appealing physical interpretation. Accurate models are derived from both physical and experimental data and decentralized control is demonstrated in the process. The effectiveness of this approach is shown by simulation results using Matlab /Simulink.
