摘要
为使运输机能在较强侧风下仍能完成空投任务,需设计抗侧风控制器减缓其对空投过程的影响。分别设计了经典的PD控制器和离散论域的模糊控制器。仿真结果表明,两者均能有效抑制侧风干扰。与PD控制器相比,模糊控制器具有更高的控制精度和较强的鲁棒性。
In order to accomplish the ultra-low altitude （ULA） airdrop task in strong crosswind, a controller should be designed to alleviate the effect of the crosswind. A classic PD controller and a Fuzzy controller in discrete domain are both designed. The simulation results show that both controllers counter the crosswind effectively. Compared with PD controller, the Fuzzy controller has higher precision and stronger robustness.
