摘　　要：现代战机普遍采用数字电传飞行控制系统进行增稳和控制。法向过载是飞控系统的重要反馈。受重力影响,法向过载传感器的测量值会随飞机姿态变化,给飞机的配平和操纵带来困难。本文以某型电传飞机为例,利用飞机姿态信息对法向过载传感器测量值进行补偿,并通过仿真验证其效果。Digital fly-by-wire flight control system is widely used on modern fighters for stability augmentation andcontrol. Normal G-load is an important feedback of the flight control system. Affected by gravity, the measuredvalues of normal accelerometer will change with aircraft attitude, which will bring difficulties to aircraft trimming andhandling. In this paper we chosea fly-by-wire aircraft as an example, compensate the measured values of normalaccelerometers by using aircraft attitude information, and verify its effect via simulation.
