摘要针对舵机间隙参数辨识问题，设计了间隙可调的试验装置模拟舵机传动机构的间隙，以静载突卸方式使其产生自由振动，应用基于希尔伯特变换的自由振动分析方法得到双折线弹性力曲线并辨识间隙参数。并进一步应用于真实飞行器舵机间隙的辨识中。该试验方法获取的振动数据信噪比良好；辨识结果表明本文方法可更为准确的识别出舵机间隙参数，工程评估结果更为安全，对于小型舵机具有良好的适用性。

Abstract：To identify clearance parameters of a control actuator system, a test device with adjustable clearance was designed to simulate clearance of a control actuator system’s transmission mechanism.Static load was exerted on it and sudden unloading made it have free vibration.The free vibration analysis method based on Hilbert transformation was used to obtain its double-fold line elastic force curve, and its clearance parameters were identified.This method was applied in clearance identification of control actuator system of an actual aero-craft.It was shown that vibration data acquired with the proposed test method have good signal-to-noise ratio; the proposed method’s engineering evaluation results are more secure; it has a good applicability for small control actuator systems.

Key words： clearance Hilbert transformation control actuator nonlinear system identification
