Abstract
AbstractPilot mishandling and actuator faults are two major factors for safe flight of the civil aircraft. To solve this problem, a fault-tolerant control (FTC) method based on incremental nonlinear dynamic inversion (INDI) is proposed. Firstly, a Hess pilot model and attitude dynamics model are established to describe pilot manipulation and aircraft attitude motions. Based on this model, an INDI control is introduced to realize the aircraft fault tolerant control. The closed-loop system is asymptotically stable. Simulation results show that INDI controllers have better tracking performances than those of NDI controllers, even in the presence of actuator failure and pilot mishandling.KeywordsCivil aircraftPilot mishandlingIncremental nonlinear dynamic inversionFault tolerant control
