Modeling and simulation of a water tank level control system

Abstract

This thesis presents a study on the identification and control of a tank-level system. A non linear model was obtained using the Levenberg–Marquardt algorithm and used for controller design. Two control strategies were developed and tested: a PID controller tuned using Particle Swarm Optimization (PSO), and an H-infinity robust controller. The simulation results showed that PSO-PID offered good performance in normal conditions, while the H-infinity controller was more effective in the presence of disturbances and uncertainties.
