摘要
针对电动负载模拟系统在科学研究和产品生产中的应用,提出了基于他励直流电动机的负载模拟系统,系统以转矩、电流双闭环复合控制为控制策略,采用内模控制方法设计了电流调节器和转矩调节器。在此基础上,借助MATLAB/Simulink对系统进行了仿真研究。主要以风机类负载为例对系统的性能进行了仿真分析,仿真结果表明,设计的系统具有响应迅速、模拟准确、可靠等特点。为搭建实际试验平台奠定了基础。
An electromotor load emulation system with separately excited DC motor was introduced. The control strategy was based on torque and current double closed-loop. And the current regulator and torque regulator were designed with internal model control. On this basis, the system was emulated by MATLAB/Simulink. Fan-type load was mainly emulated to analyze the performance of the system. There have been such features of the system that the results were showed： rapid responds, accurate emulation and credibility, ect. These efforts fix the foundation to establish the real test platform. It could be realized on the basis of the research.
