Fault-tolerant aspects of MPC

Concerns control in the event of equipment failure. Model predictive control (MPC) offers a promising basis for fault-tolerant control. Since MPC relies on an explicit internal model, one could dealing with failures by updating the internal model, and letting the online optimiser work out how to control the system in its new condition. This relies on several assumptions: that the nature of the fault can be located, and its effects modelled; that the model can be updated, essentially automatically; and that the control objectives can be left unaltered after the failure. The first 2 of these may be possible using fault detection and isolation (FDI), and the management of complex models. The technologies concerned seem to offer a very powerful combination
