Development of Control Systems for a Two-Tank System using IMC and MPC Methods

The idea of this research is to design an efficient control system for a two tank system using two advanced control approaches – IMC (internal model control) and MPC (model predictive control). The precise control of the two-tank system is crucial for desired performance and efficiency. The paper begins with an overview of the two-tank system, highlighting its dynamic behavior and the challenges in regulating simultaneously the liquid levels in both the tanks. It underlines the need for advanced control strategies for enhancing the stability and responsiveness of the system. The first part of the study presents the development of IMC controller which handles the complex dynamics and mitigates the disturbances promisingly. Finally, the MPC technique is explored for the control of considered two-tank system. The MPC uses a prediction based approach which considers the future behavior of system in decision making which makes it well-suited to handle nonlinearities and constraints. The performance of both the established controllers is also compared. All simulation work is carried out in MATLAB.
