摘要
提出一种基于数字化虚拟电机控制器的半实物实时仿真测试方法。利用现场可编门阵列(FPGA)建立三相异步电机及逆变器的虚拟电机系统模型,系统的仿真步长为1μs,逼近真实工况。在离线仿真环境MATLAB/Simulink中开发按转子磁链定向的矢量控制方法,实现RTW方式写入dSPACE控制器。搭建基于虚拟异步电机系统的硬件在环(HIL)实时仿真平台,并完成测试。在全实物平台上实施异步电机空载/负载工况下的矢量控制试验,通过与HIL试验结果的对比,验证了虚拟异步电机系统的有效性和准确性。
A semi-physical simulation platform with a closed loop control of digital motor drives was presented. A virtual asynchronous motor system model of which simulation step was 1 μs, close to the real conditions was estalished based on the field-programmable gate array （FPGA）. The hardware-in-loop （HIL） real-time simulation platform based on virtual asynchronous motor system was set up. The rotor flux oriented vector control strategies were developed in MATLAB/Simulink and wilted to dSPACE controller by RTW ways to complete the virtual asynchronous motor simulation test. The vector control experiments of no load and load conditions had been done in the asynchronous motor physical platform. By comparing HIL experimental results with physical platform ones, the validity and accuracy of the virtual asynchronous motor system has been verified.
