Performances Compared To The Sliding Mode And Gain Scheduling Control Methods Of A Cstr Chemical Reactor

In this work, For many years, the sliding mode control has been deemed as one amongst the most studied control domains. Indeed, the power and simplicity that characterize such a control are the essential coerces which often push us to search for this technique thoroughly. When synthesizing the sliding mode control law, the sliding surface is usually defined as an autonomous and stable nonlinear system. Nevertheless, the dynamics imposed by such a system is slower than that imposed by a nonlinear system. Therefore, the use of this type of systems to synthesize the sliding surface in certain applications has becomes increasingly important. This type of system is also utilized for the gain scheduling control. The very control is combined with the feedback linearizing. Indeed, the synthesized control is mainly based on the reverse trajectory method which allows estimating the domains of attraction around the operating points. In this work, as a matter of fact, we are inclined to the synthesis of control laws of a chemical reactor. In this respective, an approach to the sliding mode control is applied. Another approach to the gain scheduling control is also proposed and is, successful, applied to the considered system. The performances of both control laws are, then, compared in terms of trajectory tracking.
