Fault-tolerant control of aero-engine based on backstepping
An adaptive neural network backstepping control approach is proposed for aero-engine system with faults. A method was employed to estimate the terms of model error and fault on-line. The proposed controller is utilized to compensate the model error approximately. When a fault is detected, controller is reconstructed to accommodate the fault. Therefore, the fault influence is eliminated by the fault-tolerant controller. It is proved that the residual signal converges to an arbitrary small neighborhood around zero. Finally, the low pressure turbine speed controller is designed based on a nonlinear model of a turbofan engine. Simulation results show the feasibility of the proposed approach.
