摘要
为提高飞机起落架防滑刹车系统的效率和可靠性,针对刹车系统的复杂性及非线性的特点,提出了基于滑模变结构的全电驱动刹车防滑控制系统方案;将滑模变结构的机电设备力闭环的控制策略应用于全电驱动起落架刹车系统,以提高系统响应频率和刹车力闭环控制精度。通过惯性台刹车试验对设计的防滑刹车控制器及其控制策略进行验证。试验结果表明,设计的电刹车系统带宽由传统算法的2.5 Hz提高到7 Hz,力闭环控制精度由7.5%FS提高到2.0%FS。
In order to improve the efficiency and reliability of the aircraft's landing gear anti-skid braking system, the scheme of the all-electric anti-skid braking control system based on sliding mode variable structure is proposed, aiming at the complexity and nonlinear characteristics of the braking system. The force closed-loop control strategy of mechanical and electrical equipment with sliding mode variable structure is applied to the all-electric drive landing gear braking system to improve the system response frequency and the closed-loop control accuracy of braking force. The design of the anti-skid brake controller and its control strategy are verified by the inertial brake test. The test results show that the bandwidth of the designed electric brake system is increased from 2.5 Hz of the traditional algorithm to 7 Hz, and the force closed-loop control accuracy is increased from 7.5% FS to 2.0% FS.
