摘　　要：在不同的控制场合下,需要不同的控制电路控制步进电机驱动器,而不同的控制电路对步进电机的工作性能有很大的影响,为此设计一款集微控制器和驱动芯片于一体的多轴多细分步进电机驱动控制器来实现驱动和控制的完美结合。驱动控制器以STM32F103ZET6为主控制器,LV8727为驱动芯片,采用USB进行主控制器与上位机的数据通信,根据不同的运动方式,以不同频率的PWM控制驱动芯片实现步进电机的多细分恒流驱动控制。基于步进电机的驱动控制原理对整个系统进行建模、理论分析及仿真,并通过实验进一步验证了系统在不同场合下精确稳定的控制性能。In different control occasions,stepper motor drive＇s control needs different control circuits,which have great effect on the work performance of stepping motor,so designing a kind of multiple spindle subdivision stepper motor drive controller,which integrates micro controller and drive chip,was needed to achieve the perfect combination of drive and control. The drive controller,which used STM32F103ZET6 as main controller and LV8727 as drive chip,had data communication between the main controller and the upper machine using USB and controlled drive chip to realize step motor subdivision constant current drive control with different frequency PWM. Modeling,theoretical analysis and simulation of the whole system were established based on the driver control principle of stepper motor and accurate and stable control performance in different occasions of the system were further proved through the experiment.
