摘要: 为提高机载光电稳瞄伺服控制系统分析与设计能力,提出一种基于dSPACE半实物仿真平台的稳瞄伺服控制系统速率稳定回路建模方法。该方法通过dSPACE对系统施加激励并采集信号,用最小二乘算法拟合系统频率特性,利用MATLAB辨识工具箱辨识出系统传递函数。对某机载光电稳瞄伺服控制系统,利用本方法获取对象模型并进行控制器设计,实验结果证明了该方法的有效性和实用性。

Abstract: In order to improve the analysis and design capability for airborne stabilized aim servo control system, a modeling method based on dSPACE was introduced. The active signal was sent to the object system and the response signal was acquired by using dSPACE. The system’s frequency characteristic was obtained by least square methods and the transfer function was fit by using Ident toolbox in MATLAB. This method was used in the controller design for an airborne stabilized aim servo system, and the validity and practicability were proved by the experiment results.
