Model Predictive Control and Fault Tolerance

Abstract

Having presented and discussed the application of the MPC technique to sewer networks in previous chapters, now the occurrence of a fault in an actuator of the sewage system is considered. Therefore, tolerance strategies within the MPC theory and different aspects of the application of a fault-tolerant scheme when MPC is applied as the control law of the closed-loop scheme are discussed, before solving some problems using the proposed methodology. Note that the hybrid modelling methodology developed in Chapter 5 is used to deal with system faults and to model them so that a global solution can be found for the sewer network control problem despite the presence of faults. The expression of faults in the hybrid system framework complements the plant model and allows to take advantage of the capabilities of MPC within an FTC architecture.
