摘要
文章鉴于永磁同步直线电机具有高推力强度、低损耗、小电气时间常数,响应速度快等特点,在直线式交流伺服系统中有很好的发展前景,介绍了永磁同步直线电机在理想假设条件下的数学模型,论述了在该条件下控制永磁同步直线电机运行的两种矢量控制策略:电流正弦脉宽调制(SPWM)和空间矢量脉宽调制(SVPWM)的基本工作原理,并在Matlab/Simulink中建立了两种仿真模型,比较了在这两种控制下的仿真结果,得出了在空间矢量控制下电机运行更平稳,推力脉动小,运行精度高。
This thesis introduces the math model of Permanent Magnet Linear Synchronous Motor （PMLSM ）. It illustrates the principle of two strategies controlling PM LSM ： current sine PWM and space vector PWM, and builds the simulation models based on the M atlab/Simulink software. Comparing the analysis of the two strategies, the motor runs more smoothly, has less thrust ripple and higher precision under the control of space vector PWM.
