摘要
建立了主动控制起落架的数学模型和控制方程,应用主导极点的时域设计法对主动控制起落架中PID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 was established.A PID active controller was designed with the method of dominant top.The dynamic performances of active control system and passive system of landing gear were compared with the method of numerical simulation.The result 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.
