Design of brushless DC motor controller based on TMS320L240x DSP

采用电流环、速度环和位置环相结合的多环控制方法,在计算时采用改进的空间矢量PWM算法,设计了基于TMS320L240x DSP的无刷电机控制器。实验表明,该方法稳定了逆变器工作频率,改善了无刷电机的换相性能,实现了无刷电机的稳定快速控制。

A multi-feedback-loop control method including the current loop and rotate-speed loop combined with station loop is introduced, and adopting space-vector PWM arithmetic in calculating, and a brushless DC motor(BLDCM) control system based on TMS320L240x DSP is designed.The test approves this method stabilize the working-frequency of the inverter and the phase alternation of the BLDCM is improved, and stable-fast control of the BLDCM is realized.
