The invention discloses a multi-redundancy brake control framework and method for an airplane. A first brake controller comprises a first main control module, a first standby control module and a first emergency control module; the second brake controller comprises a second main control module, a second standby control module and a second emergency control module. The comprehensive controller and the brake controller work cooperatively, the two control modules are backups for each other, and redundancy design is added to the comprehensive controller; the three control modules in the brake controller are in redundancy design for each other, the second control module comprises redundancy design for the other brake controller, and the probability that the airplane wheel brake system completely loses brake is reduced to 7.8 E-10. Automatic brake anti-skid control is achieved through the comprehensive controller, the non-convergence phenomenon possibly occurring when two control algorithms are achieved through the same software is avoided, and the reliability of a brake system is improved. The emergency brake control module adopts a pure analog circuit and is completely different from the design of a main control module and a backup control module, so that the safety of the brake system is improved.
一种飞机多余度刹车控制架构及控制方法,第一刹车控制器包括第一主控制模块、第一备用控制模块和第一应急控制模块;第二刹车控制器包括第二主控制模块、第二备用控制模块和第二应急控制模块。综合控制器与刹车控制器协同工作,两块控制模块互为备份,综合控制器增加了余度设计;刹车控制器中的三个控制模块互为余度设计,且第二个控制模块包含为另一刹车控制器的余度设计,机轮刹车系统完全丧失刹车的概率降低到7.8E‑10。通过综合控制器实现自动刹车防滑控制,避免同一软件实现两种控制算法可能发生不收敛现象,提高了刹车系统可靠性。本发明的应急刹车控制模块采用纯模拟电路,与主控制模块和备份控制模块的设计完全不同,提高了刹车系统的安全性。
