【摘要】：电机从研制、投产、运行到维修,各阶段通过大量试验,获取设备运行参数来分析性能指标是必不可少的一步。为推动电机测试技术发展,本文提出了以现场总线控制(FCS)理论为背景,结合电机矢量控制(FOC)算法,以DSP为分布节点控制核心,基于LabVIEW平台开发的主控机监控系统,实现了永磁同步电机的分布式性能测试。本系统利用CAN总线的开放性和互换性,将现场的各测试电机和主控系统互联,构成现场总线控制系统。实现开放性通信网络和全分布式控制系统的有机统一,是现场测试和控制设备互联的纽带。现场测试电机作为FCS的网络节点挂接在总线上,主控平台通过网络对现场设备采集和发送测控信息,从而实现管、测、控一体化。在分析了电机测试系统的国内外现状及其常用的测试方法基础上,设计了基于CAN总线的永磁同步电机性能测试系统；分布节点应用DSP技术结合FOC控制算法实现了电机的运行参数采集、控制及CAN通信,测试结果验证了DSP控制器运行的高速和运算的高精度及算法的可行性；主控制节点应用虚拟仪器技术实现了测试系统的整体构建,测试结果验证了系统的开放性和可扩展性。论文以永磁同步电机作为测试对象,对所设计的测试系统进行了软硬件的联合测试。实验结果表明系统运行稳定可靠,能够通过CAN总线实现主控机对分布测试电机的动态性能测试。在电机的控制性能评估和合格检修方面,具有一定实用价值。
[Abstract]:It is an essential step for the motor to obtain the operating parameters of the equipment to analyze the performance index through a large number of tests from the development, production, operation and maintenance of the motor. In order to promote the development of motor testing technology, this paper presents a monitoring system of main control machine based on LabVIEW platform, which is based on the theory of field bus control (FCS), combined with the algorithm of motor vector control (FOC), and using DSP as the core of distributed node control. The distributed performance test of permanent magnet synchronous motor is realized. This system makes use of the opening and interchangeability of CAN bus, interconnects the test motor and the main control system in the field, and constitutes the field bus control system. The organic unification of open communication network and full distributed control system is the link between field test and control equipment. The field test motor is connected on the bus as the network node of FCS. The main control platform collects and sends the measurement and control information to the field equipment through the network, so as to realize the integration of tube, measurement and control. Based on the analysis of the current situation of the motor testing system at home and abroad and the commonly used testing methods, a permanent magnet synchronous motor performance test system based on CAN bus is designed. The distributed node uses DSP technology and FOC control algorithm to realize the operation parameter acquisition, control and CAN communication of the motor. The test results verify the high speed and high precision of the DSP controller and the feasibility of the algorithm. The master control node uses virtual instrument technology to realize the overall construction of the test system. The test results verify the openness and expansibility of the system. In this paper, the permanent magnet synchronous motor (PMSM) is taken as the test object, and the software and hardware of the test system are tested. The experimental results show that the system is stable and reliable and can be used to test the dynamic performance of distributed test motor by CAN bus. It has certain practical value in motor control performance evaluation and qualified overhaul.
