摘　　要：在飞机防滑刹车系统优化控制的研究中,由于传统的PD+PBM(比例、微分+压力偏调)控制律在低结合系数跑道上低速打滑、鲁棒性差。为提高刹车效率,提出了一种结合免疫PID控制和模糊控制的新型控制策略。以某型飞机为研究对象,对防滑刹车系统主体部分进行原理分析并建立模型,采用新型免疫控制器完成了控制回路的设计,并在MATLAB/SIMULINK仿真环境下进行系统仿真。仿真结果表明,改进控制方法能够很好的改善传统控制律的不足,有效的减缓打滑现象,减少机轮打滑时间,提高了系统的刹车效率。For optimal control of aircraft anti - skid braking system, the traditional PD ＋ PBM （ Proportion Differentiation ＋ Press Bias Module）control has the problem of poor robustness and low speed skid on the low coefficient road. Considering those defects, a new control algorithm combined with immune PID control and fuzzy control is proposed. In the present study, the principle of anti - skid braking system is analyzed and the corresponding model is established for a certain type of aircraft. The design of the control loop is accomplished based on new pattern immune controller and simulated in MATLAB/SIMULINK software. The simulation results show that the control method can efficiently overcome the shortcomings of traditional control algorithm, slow down the skid phenomenon, reduce the skid time and improve the braking performance.
