Abstract:

For the problem of sensor faults and actuator faults in aircraft attitude control, this paper proposes a fault tolerant control (FTC) scheme based on extended state observer (ESO) and nonlinear dynamic inversion (NDI). First, two ESOs are designed to estimate sensor faults and actuator faults respectively. Second, the angular rate signal is reconstructed according to the estimation of sensor faults. Third, in angular rate loop, NDI is designed based on reconstruction of angular rate signals and estimation of actuator faults. The FTC scheme proposed in this paper is testified through numerical simulations. The results show that it is feasible and has good fault tolerant ability.

Key words: fault tolerant control (FTC), signal reconstruction, extended state observer (ESO), nonlinear dynamic inversion (NDI)
