基于DSP的步进电机控制

Stepper Motor Control Based on DSP

论文首先叙述了步进电机的工作原理,介绍了其驱动和控制电路,重点论述了以TMS320VC5402DSP为核心来实现步进电机的正反转的设计,运用自动控制理论和DSP技术,通过IO总线锁存产生的脉冲的频率与相位的顺序控制速度与方向,借助CCS开发环境,用DSP TMS320VC5402开发板的硬件控制电机的不同运动状态,并给出了主程序的代码。试验证明这个方法可行有效。

In order to introduce the drive and control circuit,the paper briefly describes the working principle of stepper motor and describes the positive and negative rotation of the stepping motor which can be realized by the TMS320VC5402 DSP which is the core of the system.With automatic control theory and DSP technology,it controls speed and direction through the IO bus latch which produces pulse frequency and phase of sequence,under CCS development environment,different working states of DC motor can be controlled by DSP TMS320VC5402.Main programs have been given.Experimental results prove this method is feasible and effective.
