A fault tolerant control method is proposed in this paper for a turbofan engine gas path degradation through the full flight envelope.A Quantum-behaved Particle Swarm Optimization(QPSO)algorithm is applied to obtain engine inputs adjustments,which contribute to construct off-line performance accommodation interpolation schedules.With a double closed-loop control system structure,command control is corrected based on real-time fault diagnostic results.Simulations indicate that fault tolerant control could reduce thrust and stall margin loss effectively in gas path faults.
