基于DSP的永磁无刷同步电机的控制系统

A control system of permanent magnet synchronous motor based on DSP

讨论了采用新一代 DSP(TMS3 2 0 LF2 4 0 7)设计三相永磁无刷同步电机控制系统的方案及电机位置信号的确定方法 ,给出了控制系统结构原理图 ,分别用软件和硬件实现 ,探讨了磁场定向控制。

This paper presents in detail a control system of a 3-phase permanent magnet synchronous motor using TMS320LF2407 DSP, and shows a basic figure of the control system.An introduction about a hardware and software solution to the motor control using DSP is given.A solution to the accurate rotor position of the motor is also discussed.Field oriented control is chosen to be the strategy to control the motor. The space vector PWM is used to generate pseudo sinusoidal currents in the stator phases.
