Study of intelligent vector control system based on TMS320F240

Abstract

According to the characteristic of alternating current permanent magnet synchronous motor (PMSM), this paper presents a practical solution of permanent magnet motor intelligent vector control using the TMS320F240 digital signal processor (DSP). Here DSP can finish fully digital control of the space angle and amplitude components of stator field together with a single neuron operation. It concretely elucidates implementation of both intelligent vector control system and producing space vector pulse width modulation (SVPWM) wave. Experimental results show that the system has good real-time quality and feasibility, and the chip has notable advantages of application in the digital motor control system.
