永磁同步电机SVPWM控制系统仿真设计(任务书,论文12000字)
摘要
针对永磁同步电机（以下简称“PMSM”）的SVPWM（空间矢量脉宽调制）控制系统设计问题，通过PMSM物理模型、数学模型的建立，采用定子三相静止坐标系转换为两相静止坐标系（3s/2s），再由两相静止坐标系转换为两相旋转坐标系(2s/2r)，建立了PMSM的动态模型。基于空间矢量脉宽调制（space vector pulse width modulation,SVPWM）的基本原理，设计了基于PI控制器的PMSM的SVPWM调速系统，利用Matlab/Simulink仿真平台，采用经典速度、电流双闭环控制方法，完成了SVPWM调速系统的设计和仿真，进一步初步探究了转子角速度、转矩、三相定子电流及电流空间矢量分量的响应情况。
设计的仿真结果表明：系统构建方法直观简单，基于SVPWM控制的PMSM系统响应速度快，系统运行平稳，仿真波形同理论分析一致，初步验证了该平台的有效性。

Abstract
Arming at the problem of SVPWM (space vector pulse width modulation) control system design for permanent magnetic synchronous motor (PMSM),through the construction of mathematical models and physical model of PMSM，and the conversion of the stator’s three-phase stationary coordinate system and two-phase stationary coordinate system (3s / 2s), and then converted from two-phase stationary coordinate system to two-phase rotating coordinate system (2s / 2r), the dynamic model of PMSM was established. Based on the basic principle of space vector pulse width modulation (SVPWM), the SVPWM speed regulating system of PMSM based on PI controller is designed. Using Matlab / Simulink simulation platform, classical speed and current double closed-loop control method is adopted, The design and simulation of the SVPWM speed regulating system are completed. The response of the rotor angular velocity, torque, three-hase stator current and current space vector component are further investigated.
The simulation results show that method of building the system is simple and fast, and the response speed of PMSM system based on SVPWM control is fast, the system runs smoothly, and the simulation waveforms are consistent with the theoretical analysis, which proves the validity of the platform.
