摘要
介绍了基于TMS320F2806芯片控制的步进电动机的细分驱动系统,利用电流合成矢量的旋转法实现了高精度细分方案。开发了两相混合式步进电机的硬件电路,反馈部分采用了高精度的电流互感器对电流采样;实现了控制系统的电流闭环PI调节算法。最后,对系统进行了实验研究,表明该系统运行平稳,电流波形良好,噪声低,定位精度高。
A system of division driver method based on Tms320F2806 was proposed.Through adopting the methodnamed ＂Current vector even rotation with uniform amplitude＂,the system featured highly precise division.The hard-ware system for two-phase hybrid stepping motor was developed.The high-precision hall current sensor was appliedfor feedback unit to sample the winding current.The regulation algorithm of closed-loop current of control system wasalso realized in the end,and a large amount of experiments were carried on.The result indicated the system runsmoothly,and the performance of the stepping motor at low frequency was also improved.
