摘　　要：根据两相混合式步进电机细分驱动原理,设计了一种基于STM32F103RB单片机的、细分度可调的步进电机驱动器。控制器采用电流矢量控制算法,通过双H桥驱动步进电机的两相转子。利用片内AD对电机转子电流进行采样,将矢量角度的目标值与测量值进行比较、调节,形成电流环,进而实现对整个周期电流阶梯的细分度控制。本文还介绍了该控制器的软硬件设计方案,并对该设计的实际电路进行了测试,结果表明控制器达到了设计目标,减少了低频振荡,提高了步进电机的控制性能。This paper describe the principle of the stepper motor＇s micro-stepping and designs a driver system which numbers of step can be adjusted based on STM32F103RB. The system used the current vector algorithm , using the dual H-bridge to connect the motor＇s rotor and through the on-chip AD to sample the MOSFET current,then take the value of vector and angle to compare and adjust with the measure one, thus forming the current loop and achieve that control the step of current to control the micro-stepping degree. The system hardware and software was designed by this theme, we debugged it and the result is this controller can improve the motor＇s inherent mechanical step angle, reduce the low-frequency oscillation and enhance the control performance.
