摘　　要：舵机装置在实际投入使用前需进行频域特性测试以获取其有效控制信号带宽,传统测试模式将测试过程分为了控制舵机运行获取数据和数据分析两个步骤,中间穿插较多的人工操作。采用了QT软件与MATLAB混合编程的方式,设计了舵机装置的频域特性测试软件,通过扫频信号控制舵机装置运行并同步在软件内得出数据分析结果。相较于传统测试方式,设计的软件有效地将两个步骤聚合到一个系统中,减少了流程间一些繁琐的人工操作。最终,实际测试结果表明,获取的各项参数与预期结果相符。In order to obtain the effective control signal bandwidth,the frequency response of the steering system should be tested before it is put into use.In the traditional testing mode,the testing process is divided into two steps:data acquisition and data analysis,with more manual operation in the middle.In this paper,a frequency response testing software of steering gear is designed with QT software and MATLAB hybrid programming,control the steering gear system with frequency sweep signal and then achieve the analysis result in the testing software.Compared with the traditional testing method,the software designed in this paper effectively aggregates two steps into one system,reducing some tedious manual operations between processes.Finally,the actual test results show that the obtained parameters are consistent with the expected results.
