Abstract :
This article presents an easy way to control integrating systems using a sliding mode controller based on a first-order-plus-dead-time (FOPDT) model of the process. A simple method of system identification is proposed to obtain the FOPDT model parameters. A set of tuning equations for the controller are established as functions of the parameters. Finally, an integrating chemical process is simulated and the proposed controller´s performance is judged
