A fly-by-wire flight control system and method are disclosed. The main computer calculates a control surface control instruction according to manipulation input, and the first secondary computer and the second secondary computer generate a first control surface driving signal and a second control surface driving signal respectively based on the control surface control instruction provided by the main computer. The second secondary computer is non-similar to the first secondary computer. And the first actuator and the second actuator drive the aircraft control surface according to the first control surface driving signal and the second control surface driving signal respectively. The first actuator and the second actuator may include different types of actuators. Under the working condition of power supply failure of the main power supply or common-mode failure of the first secondary computer, the standby power supply of the second secondary computer can be activated to ensure that the aircraft can still fly and land safely. A fly-by-wire control method is also disclosed.

    公开了一种电传飞行控制系统和方法。主计算机根据操纵输入来计算舵面控制指令,第一次级计算机和第二次级计算机分别基于主计算机提供的舵面控制指令来生成第一舵面驱动信号和第二舵面驱动信号。第二次级计算机与第一次级计算机是非相似的。第一作动器和第二作动器分别根据第一舵面驱动信号和第二舵面驱动信号来驱动飞机舵面。第一作动器和第二作动器可包括不同类型的作动器。在主电源供电故障或第一次级计算机共模故障工况下,可激活第二次级计算机的备用电源,保证飞机仍能安全飞行和着陆。还公开了电传飞行控制方法。
