【摘要】：與異步電動機相比，永磁同步電機具有功率密度高響應速度快節(jié)能等優(yōu)點，由永磁體產(chǎn)生磁場而不需要勵磁繞組，因此在同等功率下電機體積更小同步電機不存在轉(zhuǎn)差率，控制起來更加簡單方便，因此永磁同步電機調(diào)速系統(tǒng)逐漸成為現(xiàn)代中小功率調(diào)速系統(tǒng)的主流而高性能微處理器大功率電力電子技術和先進控制技術的發(fā)展，為高性能交流永磁同步調(diào)速系統(tǒng)的發(fā)展提供了條件 本文研究的永磁同步電梯曳引機應用于電梯領域，主要運行于低速大轉(zhuǎn)矩場合，對速度響應速度和轉(zhuǎn)矩輸出要求很高，本文基于永磁同步電梯曳引機,進行了控制系統(tǒng)的研究和設計，使設計的驅(qū)動系統(tǒng)能夠滿足電梯運行的性能要求 本文首先介紹了永磁同步電梯曳引機的分類和結(jié)構(gòu)特點，簡單介紹了國內(nèi)外電梯曳引機和永磁同步電機控制的研究現(xiàn)狀然后對永磁同步電梯曳引機的數(shù)學模型進行了理論分析，選擇按轉(zhuǎn)子磁場定向的矢量控制策略作為本系統(tǒng)的控制策略搭建控制系統(tǒng)的方框圖，對電機參數(shù)辨識轉(zhuǎn)子磁極位置辨識死區(qū)補償和過調(diào)制策略進行了數(shù)學推導在第三章以TI公司TMS320F2803x系列DSP為控制核心，分主功率驅(qū)動電路和控制電路對曳引機控制系統(tǒng)硬件平臺進行了詳細的設計第四章介紹了本系統(tǒng)的軟件平臺，，給出了轉(zhuǎn)子磁極位置辨識過調(diào)制和正余弦編碼器細分插值的算法流程第五章以仿真和實驗的方式，證明所設計的控制系統(tǒng)滿足電梯系統(tǒng)的運行特性和性能要求，電梯運行具有良好的乘載舒適感
[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.
