For nonlinear systems without hardware redundancy, a fault tolerant control design based on MPC (model predictive control) against actuator failures is presented. The nonlinear system is decoupled by a static state feedback. Then MPC algorithm is designed for the decoupled system. In case of actuator failures, the reference inputs are recomputed by using MPC algorithm, to maintain the system at some acceptable level of performances. The approach is used to three-tank plant, the results shows… CONTINUE READING
