通过分析电传飞控系统在实现不同功能下的控制回路稳定裕度评估方法，给出了在姿态保持功能下进行稳定裕度评估时所需观测点的选取思路。通过简化真实飞机纵向控制律及飞机方程，建立测试模型，经过仿真分析和验证，提出了带有姿态保持功能的飞控系统稳定裕度的评估方法。该方法已应用于某型号飞机地面试验。

Because the control loops are different when the system implements different functions, the methods to estimate stability margin of the FBW control system have differences. By comparing the different methods, the article presented an approach how to choice the test point for the control loop which can implement attitude hold function in order to estimate the stability margin. The real control laws and the aircraft motion equations were simpliifed , and the model was build. Finally the methods for estimating stability margin of the FBW control system with attitude hold had been proposed through simulation analysis. Furthermore, the methods has been used on the ground tests of the plane.
