摘要 针对舰载机在着舰下滑时飞行轨迹不稳定、在控制升降舵的同时还需要进行发动机推力补偿的问题,建立了舰载机纵向着舰飞行姿态运动模型,采用自抗扰控制技术对着舰飞行控制系统进行解耦。首先,将俯仰角回路和迎角回路中的耦合项视为扰动,设计扩张状态观测器对回路中的状态量和总扰动进行估计;然后,采用非线性状态误差反馈律和扰动实时补偿来计算虚拟控制量,并通过控制分配得到升降舵和发动机推力控制量。仿真结果表明,在升降舵偏转角和发动机推力可用的范围内,所设计的姿态控制系统和动力补偿系统能使航迹角快速、准确地跟踪姿态角指令。 Due to the instable flight path of carrier-based aircraft when approaching,the thrust must be compensated while controlling elevator. Based on the longitudinal carrier-landing flight attitude dynamic model,the active disturbance rejection control was used to decouple the carrier-landing flight control system. Firstly,the coupling component in the pitch angle loop and angle of attack loop were regarded as disturbance. The states and total disturbances were estimated by the extended state observer. Then,the estimated total disturbances were compensated in the nonlinear state error feedback to calculate the virtual control inputs. The control inputs of elevator and thrust were calculated by the control allocation. Simulation results show that the designed attitude control system and auto power compensation system could make the flight path angle follow the pitch angle command rapidly and strictly,while the elevator and engine are available.
