【摘要】：与异步电动机相比，永磁同步电机具有功率密度高响应速度快节能等优点，由永磁体产生磁场而不需要励磁绕组，因此在同等功率下电机体积更小同步电机不存在转差率，控制起来更加简单方便，因此永磁同步电机调速系统逐渐成为现代中小功率调速系统的主流而高性能微处理器大功率电力电子技术和先进控制技术的发展，为高性能交流永磁同步调速系统的发展提供了条件本文研究的永磁同步电梯曳引机应用于电梯领域，主要运行于低速大转矩场合，对速度响应速度和转矩输出要求很高，本文基于永磁同步电梯曳引机,进行了控制系统的研究和设计，使设计的驱动系统能够满足电梯运行的性能要求本文首先介绍了永磁同步电梯曳引机的分类和结构特点，简单介绍了国内外电梯曳引机和永磁同步电机控制的研究现状然后对永磁同步电梯曳引机的数学模型进行了理论分析，选择按转子磁场定向的矢量控制策略作为本系统的控制策略搭建控制系统的方框图，对电机参数辨识转子磁极位置辨识死区补偿和过调制策略进行了数学推导在第三章以TI公司TMS320F2803x系列DSP为控制核心，分主功率驱动电路和控制电路对曳引机控制系统硬件平台进行了详细的设计第四章介绍了本系统的软件平台，，给出了转子磁极位置辨识过调制和正余弦编码器细分插值的算法流程第五章以仿真和实验的方式，证明所设计的控制系统满足电梯系统的运行特性和性能要求，电梯运行具有良好的乘载舒适感
[Abstract]:Compared with the induction motor, permanent magnet synchronous motor has high power density and energy saving advantages of fast response, by the permanent magnet magnetic field without excitation winding, so the motor in the same power, smaller synchronous motor slip control does not exist, more simple and convenient, so the permanent magnet synchronous motor speed control system has gradually become the mainstream of modern small and medium power control system of the high performance microprocessor power electronic technology and advanced control technology development, provided the conditions for the development of high performance PMSM speed control system
This paper studies the PMSM lift machine used in elevator field, mainly operating in low speed and high torque applications, high speed of response speed and torque output, the permanent magnet synchronous traction machine of elevator based on research and design the control system, the drive system design can meet the performance requirements of elevator operation
This paper first introduces the classification of permanent magnet synchronous elevator traction machine and structure, introduces the domestic and foreign research status of the elevator traction machine and permanent magnet synchronous motor control and then makes a theoretical analysis of the mathematical model of permanent magnet synchronous elevator traction machine, according to the selection of rotor flux vector control strategy as the control strategy of the system set up the control system block diagram, the motor parameter identification of rotor position identification of dead time compensation and over modulation strategy are deduced in Chapter third with TI company TMS320F2803x series DSP as control core, drive circuit and control circuit of the hardware platform of control system of traction machine has carried on the detailed design of the fourth chapter introduces the system software platform the main power, given rotor position identification and modulation cosine encoder subdivision interpolation algorithm in the fifth chapter, process simulation and real It is proved that the designed control system meets the operating characteristics and performance requirements of the elevator system. The elevator operation has a good ride comfort sense.
