为解决恶劣条件下飞机滑跑纠偏的控制问题,提出采用方向舵偏转、主轮差动刹车和前轮转向的联合纠偏控制方案和控制结构,设计各个子系统的纠偏控制律,然后根据各系统在不同速度段的控制效率,引入影响因子将三者进行综合;在分析飞机地面滑跑受力的基础上,建立全面反映飞机滑跑运动特性的动力学模型及地面操纵模型。最后以某运输机为研究对象,进行地面滑跑建模和综合纠偏控制仿真验证。仿真结果表明,地面滑跑模型符合实际过程,综合纠偏控制方案可以实现滑跑纠偏的有效控制,远比单独控制的效果要好。

To solve the problem of aircraft deviation correction under bad conditions, a combined deviation-correction control scheme and structure was proposed which employed rudder deflection, main-wheel differential braking and front-wheel steering in this paper. Firstly, the corrective control law of each subsystem was designed, and then according to the control efficiency of each system in different speed segments, the influence factor is introduced to integrate the three. On the basis of the analysis of the aircraft's taxiing force, a dynamic model and ground control model that fully reflect the characteristics of the aircraft's taxiing motion were established. Taking a transport aircraft as the research object, the ground running modeling and comprehensive deviation correction control simulation verification were carried out. The simulation results show that the ground running model was in line with the actual process, and the comprehensive deviation correction control scheme can realize the effective control of deviation correction, which was better than the single control effect.
