摘　　要：以飞机全电刹车为研究背景,采用滑模变结构控制策略,设计刹车防滑控制策略,解决传统刹车效率低、机轮深度打滑、低速刹车性能差等问题。在控制策略中,以最佳滑移率为目标函数,设计滑模面,实现刹车防滑控制。由于滑模控制的强鲁棒性,可有效提高系统的抗干扰能力。仿真结果可知,滑移率控制在最佳滑移率附近,刹车效率高,可消除机轮深度打滑现象,防滑效果优良。In the research dopted. Anti-skid braking background of all-electric braking for aircraft, the sliding mode control strategy is acontroller for aircraft is designed to solve the defects of traditional brakes such as low efficiency, depth wheel skidding, poor braking performance at low speed. In the control strategy, the most opti- mal slip rate is used as the objective function to design sliding surface, and anti-skid braking control is achieved. Due to the strong robustness of sliding mode control, the anti-interference ability of the system is effectively improved. The simulation results show that when the slip rate control stays near most optimal slip rate, the brake efficiency is high, the phenomenon of depth wheel skidding is eliminated, and the effect of anti-skid braking is good.
