摘 要：When naval vessels moving on the sea, the carrier air wake disturbance will arise. The carrier air wake makes the landing environment of carrier aircraft fair adverse, which puts forward a high demand for the high precise attitude control of carrier based aircrafts. In this paper, high precise robust attitude control problems for carrier based aircrafts with the carrier air wake disturbance are investigated. Firstly, the small disturbance linearization method is introduced to transform the nonlinear system into a linear one, which is a necessary procedure for aircraft system analysis and controller design. Secondly, the model of the carrier air wake disturbance is established and its effects on the aerodynamic parameters are analyzed in detail. Then the effects are transformed into the augmented disturbance in the system. Thirdly, a nonlinear extended state observer is utilized to estimate the disturbance. Besides, a robust adaptive attitude controller with integral term is proposed to achieve high precision attitude tracking. The stability of the closed-loop system is prove based on Lyapunov theory. Finally, a numerical example is provided to demonstrate the effectiveness of the obtained results.
