Operator-based Robust Fault Tolerance Control for Uncertain Nonlinear Microreactors with Coupling Effects

Peltier devices are applied to overcome the shortages of the heat transfer and vibration to solve the difficult control problem of Microreactor systems. However, the uncertainties and coupling effects of the microreactor systems have not been considered. And it is necessary to detect and isolate the fault signals which may have a bad effect on the control systems. Based on the above considerations, operator-based control scheme, compensation of uncertainties, elimination of coupling effects and nonlinear fault tolerance method are applied to construct the whole control system. By using this proposed control system, the temperature tracking performance, stability and robust stability can be guaranteed even when the fault signals exist. The results of the experiments are presented to demonstrate the effectiveness of this proposed control system.
