Fault-tolerant cooperative control: a distributed model predictive control approach
Résumé
In this paper, a distributed networked control system architecture based on unsupervised and independent Model Predictive Control/Robust Adaptive Fast Fault Estimation (MPC/RAFFE) schemes is proposed. In this distributed framework, local MPCs algorithms might exchange and require information from other sub-controllers via the communication network to achieve their task in a cooperative way. The proposed distributed control tied with diagnosis tasks yields a suitable architecture for fault tolerant control (FTC) in large and interconnected systems. The insight gained from the design of such architecture is used to implement active FTC (AFTC) under actuator faults. Finally, numerical test simulations are given to validate the distributed MPC/RAFFE architecture.
