摘要
建立了主动控制起落架的数学模型和控制方程,对主动控制起落架中前馈反馈控制器进行了设计,并分别对被动式和主动式起落架的输出位移、输出速度、输出力进行了仿真比较分析,仿真结果说明主动控制起落架能降低飞机的冲击载荷和振动响应,降低飞机对跑道的要求。
The mathematical model and control equation of active control landing gear is established. A feed-forward and feed-back active controller is designed. The dynamic performances of active control system and passive system of landing gear are compared with the method of numerical simulation. It shows that the impact load and vibration load can be reduced and the performance of the system can be improved by adopting active control landing gear.
