分析了舰载机进场动力补偿系统的必要性,给出了一种基于趋近律的离散时间滑模变结构控制方法。利用该方法设计了一种保持地速迎角恒定的舰载机进场动力补偿系统,建立了舰载机自动着舰的综合仿真模型。仿真结果表明,通过控制俯仰角的变化量,能够使舰载机快速准确地沿着理想的下滑轨迹着舰,该动力补偿系统能够有效抑制舰尾气流扰动的影响,具有较强的鲁棒性。 The necessity of power compensation system for carrier aircraft is analyzed. A discrete time sliding mode variable structure control method based on the approach law is given. This method is used to design a power compensation system for the carrier-borne aircraft with a constant ground-attack angle of attack, and a comprehensive simulation model for the automatic carrier-based aircraft carrier is established. The simulation results show that by controlling the variation of pitch angle, the carrier-based aircraft can be rapidly and accurately landed along the ideal gliding trajectory. The dynamic compensation system can effectively restrain the influence of airstream disturbances and has strong robustness .
