【摘要】 IRMCK201是IR公司专门为交流永磁同步电机驱动开发的控制芯片。与使用通用MCU/DSP相比,可以简化系统设计,缩短产品的开发周期。然而由于伺服控制系统的复杂性以及IR公司技术支持的不足,要实现高性能的交流永磁同步电动机控制,必须深入分析和正确设置IRMCK201的各种参数。本文以110SFM-E02030三相交流永磁同步电动机(PMSM)为控制对象,通过对交流永磁同步电动机数学模型的分析及其控制理论的研究,首先在MATLAB/simulink中做了伺服系统的仿真实验,仿真结果表明矢量控制方法具有良好的动静态控制性能。然后设计并开发了基于IRMCK201的交流伺服控制系统,此系统选用IR公司的智能功率模块作为驱动电路的核心器件,采用PIC30F2010作为人机界面和测试系统的主控芯片,通过SPI通信方式完成对IRMCK201的参数设置和状态读取,从而实现对电机运行的控制。文中详细阐述了伺服系统的驱动电路、检测电路、保护电路、显示电路和电源电路等硬件电路的设计方法。最后,开发了伺服系统的软件部分,包括系统主程序、显示子程序以及PIC30F2010与IRMCK201的通讯程序等。系统在以速度模式运行时,恒转速控制与恒转矩控制是两种主要的应用。针对这两种应用,用磁粉制动器作为负载设计制作了交流永磁同步电动机性能测试系统。对不同情况下的系统运行性能进行了测试,并对测试结果进行了分析。更多还原

【Abstract】 IRMCK201 is designed to development of permanent magnet synchronous motor drive control chip by IR company. Compared to the general-purpose MCU / DSP, it can simplify system design, shorten product development cycles. However, due to the complexity of the servo control system and the lack of technology support from IR company, to achieve high-performance PMSM control, a variety of parameters of IRMCK201 must be set correctly and analysis deeply.This paper takes 110SFM-E02030 3-phase ac permanent magnet synchronous motor (PMSM) as control object and studys the research of model of PMSM & its control theory. Firstly Simulation results show that the vector control method has a good dynamic control performance through servo system simulation experiment in MATLAB/simulink. Secondly the ac servo control system based on IRMCK201 has been designed and developed. We select IR company’s intelligent power module as the core device of driving circuit, using PIC30F2010 as the main control chip of human-machine interface and test system, through SPI communication mode to the realize the state parameter setting and reading of IRMCK201. We designed drive circuit of servo system, detection circuit, drive circuit protection circuit and display circuit hardware structure detailedly .Thirdly we developed software components of the servo system ,including the system master program, PIC30F2010 communication program with IRMCK201.In speed mode of System, the constant speed control and constant torque control are the two main applications. For both applications, the magnetic powder brake designed as a load in PMSM performance test systems. The performance of system is tested under different conditions, and test results are analyzed.更多还原
