Control of a bioreactor using static and dynamic sliding mode controllers

Abstract

The paper deals with the control of a bioreactor. Three sliding mode control schemes are proposed for the bioreactor benchmark problem. The first two controllers are static sliding mode controllers; the third controller is a dynamic sliding mode controller. The three controllers guarantee the asymptotic convergence of the states of the system to their desired values. Simulation results are given to illustrate the effectiveness of the proposed controllers. It is found that the proposed control schemes work well for the benchmark bioreactor problem. Also, the simulation results indicate that the proposed schemes are robust to variations in the parameters of the plant.
