| Abstract: | Based on the study of aircraft longitudinal stress and motion, the mathematical model of an aircraft longitudinal position in high-altitude cruise process was constructed. Aiming at possible sensor faults and parameter perturbation ,and taking the tracking control problem into account, the model of system was extended by using tracking error. Based on the construction of the state observer, a robust fault tolerant controller for aircraft longitudinal position sensor faults was obtained. Simulation results showed that when the parameter perturbation and sensor faults took place, the system could attain prompt stability with satisfying dynamic, steady performance and superior robustness. |
