摘　　要：针对多个步进电动机的协同工作问题,研究了基于DSP的三自由度的两相混合式步进电动机驱动控制系统。该系统能够对每个自由度进行完全独立的控制,而不会相互影响。每个自由度都采用细分驱动技术,并通过斩波恒流技术实现绕组电流的精确控制。实验结果与理论分析相符合,实现了每个自由度的完全独立控制,电机能够在较宽的转速范围内平稳运转。According to collaborative work problem of multiple stepper motor,a drive system of three-degree-of-free- dom two-phase hybrid stepper motor was researched based on DSP. The drive system can control each degree of freedom in- dependently without interaction. The subdivision drive method was applied in each degree of freedom and the current of winding was accurately controlled by the technology of wave copper and constant current. The results of experiments conform to the analysis of theory, and the system can control each degree of freedom entire independently. The motor can steady run in a wide speed range.
