Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 89 === The traditional linear control for the temperature control of a maleic anhydride fluidized bed reactor can’t provide predicted result cause of highly nonlinear behavior. In order to control this system, we attempt to use nonlinear controller instead of linear controller.
Recently, proposed nonlinear control methods for the system contain feedback linearization control, internal model control based on nonlinear model, Lyapunov-base control, sliding mode control, etc.
But, in this article, we compared the design difference between linear transform and original model based on
backstepping control method and proposed some different tuning
algorithms to find out the optimum adjust parameters. As we can see after adjusting controller parameters, no mater at set point tracking and uncertainty exist or not, it can makes the control performance more better.
