Abstract :
In this work, we focus on monitoring and handling of actuator faults in a distributed model predictive control (DMPC) system to maintain operation at a desired steady state in the presence of control actuator faults. A model-based fault detection (FD) system is designed which detects the actuator faults in the closed-loop system and suitable strategies are devised for how to reconfigure the algorithms in the DMPC system to account for the faults and maintain stability of the closed-loop system. A chemical process example, consisting of two continuous stirred tank reactors (CSTR) and a flash tank separator with a recycle stream, is used to demonstrate the approach.
