Operator based fault detection and isolation for microreactor actuated by Peltier devices

In this paper, the method of fault detection and isolation for microreactor units actuated by Peltier devices is proposed. Modeling and operator-based right coprime factorization of the nonlinear microreactor process are investigated. The effects of uncertainties and coupling effects of the process are controlled by the proposed design method, and the estimated output (sensorless part) is realized. Then using the proposed method of fault detection and isolation, desired output is obtained by comparing the sensor output and the estimated output. The effectiveness of the proposed design scheme is confirmed by the simulation results.
