摘　　要：设计了一种用于振荡器的驱动控制方案。简要说明了关键器件选型;介绍了以CAN总线作为通信方式的控制电路总体设计;详细阐述了电机驱动设计;分析了步进电机使用时需要关注的主要问题并提出了相应的解决方法;针对步进电机升降速控制,给出了适合本系统的控制算法。实验证明,本套驱动控制方案能够合理地实现所选步进电机的驱动功能,振荡器能够将托盘内的液体样品充分混匀。A driving control scheme for the oscillator is designed in this paper. The selection of key devices is described briefly. This paper introduces the overall design of the control circuit, elaborates the motor driving method in detail, analyses the main concerns in using and proposes the appropriate solutions. In addition, the paper introduces the control algorithm suitable for this system for the motor acceleration and deceleration control. The Experiment result verifies that this driving Control method can implement the driving function of the selected stepper motor, and the oscillator can mix the liquid samples thoroughly.
