研究飞机防滞刹车系统优化控制问题,由于飞机防滞刹车系统存在非线性特点,影响刹车系统的稳定性和控制的性能,造成飞机的着陆安全控制的较大困难。采用传统PID(比例、积分、微分)控制的飞机刹车参数整定困难,刹车效率低下,系统的鲁棒性差,现代飞机的起降重量与速度越来越大,在刹车低速阶段存在机轮抱死打滑现象,影响降落安全。针对于此,使用模糊免疫PID控制方法,以期改善飞机刹车低速阶段性能。仿真结果表明,可以较显著的改善飞机刹车的低速阶段性能,减少刹车低速阶段机轮打滑时间,缩短刹车距离,为飞机防滞刹车优化系统的设计提供了可靠依据。
Research on optimization control of aircraft anti-brake system has great difficulties in landing safety control of aircraft due to the non-linear characteristics of anti-brake system of aircraft, affecting the stability of braking system and the performance of control. The traditional brake parameters of the aircraft (proportional, integral, derivative) are difficult to set, the brake efficiency is low, the system’s robustness is poor, the weight and speed of the take-off and landing of modern aircraft are increasing, and the wheels are locked at low speed Slipping phenomenon, affecting the safety of landing. In view of this, the fuzzy immune PID control method is used in order to improve the performance of aircraft braking at low speed. The simulation results show that it can significantly improve the low-speed performance of the aircraft brake, reduce the wheel slipping time and shorten the braking distance in the low-speed braking stage, which provides a reliable basis for the design of the aircraft anti-straggle brake optimization system.
