Abstract:
This research presents the application of Generic Model Control (GMC) with Kalman filter for the control of the temperature of a reversible exothermic, first order reaction in a continuous stirred tank reactor (CSTR), which exhibits highly nonlinear behavior, and that of an irreversible exothermic, first order reaction in a continuous stirred tank reactor. The latter composed of three cases: firstly exhibits extreme parametric sensitivity behavior, secondly exhibits ignition and extinction behavior for an open-loop system, and finally exhibits nonlinear oscillation at certain operating conditions. The goals of this thesis are to design Generic Model Controller with Kalman filter which can give a good control performance and guarantee the stability of closed-loop nonlinear continuous time systems subject to constraints. Several different problems have been considered, such as control performance, disturbance rejection, setpoint tracking and parametric model/plant mismatch, etc. Simulation results have shown that the Generic Model Controller with Kalman filter provides better control performances than the conventional PID controller, especially for the cases of disturbance rejection and setpoint tracking. In addition, the Generic Model Controller is more robust than the PID in presence of model/plant mismatch.
