Abstract
In this paper, control of liquid level for a four-tank system with respect to disturbances is studied, where constrained output feedback H∞ control of linear systems based on linear matrix inequality is adopted. In contrast, both an unconstrained H∞ controller and decentralized PID controllers are applied to the four-tank system. The simulation results illustrate the effectiveness of constrained output feedback H∞ control strategy.
