Open loop control of space-vector pulse width modulation based on DSP

空间矢量脉宽调制(SVPWM)技术是一种新型的脉宽调制技术,在异步电机和同步电机的控制应用场合中,已成为用于控制三相电压源逆变器非常流行的PWM技术,本文采用高速度的DSP控制器TMS320F243对空间矢量脉宽调制(SVPWM)进行开环控制,成功实现了对伺服系统的转速和位置的精确控制.

SVPWM (The Space Vector PWM ) is one new type pulse duration modulation technology that has been so popular a technology used in controlling three-phase voltage source inverters on condition where asynchronous motors or synchronous motors are applied. This paper introduces high-speed DSP controller TM320F243 to modulate space vector pulse width with open loop control scheme, eventually successfully implementing the accurate speed and position control of the servo system.
