| 摘 要： | 利用最小二乘参数估计原理对调距桨电液伺服系统进行系统参数辨识。基于开环辨识、闭环验证的思路,设计出辨识试验方案,利用MATLAB系统辨识工具箱对采集到的数据进行预处、模型定阶和ARX参数估计,获得系统开环模型；利用Simulink对辨识得到的模型进行闭环仿真,将仿真结果与台架实验数据进行对比分析。初步尝试了系统辨识在调距桨伺服系统上的应用。

| Abstract: | Least square method was used to identify the model of the electro-hydraulic servo system of controllable pitch propeller. Based on the method of identify in opened-loop and test in closed-loop, a experimental scheme for Identification was given. Matlab was used for data processing, to ensure the order and estimate the parameters. Finally a opened-loop model was obtained. Then, the model was closed and simulated, and compared with the data from the test bench. |
