摘　　要：基于提高两相混合式步进电机的稳态性能和动态特性的目的,本文结合转矩矢量控制策略,提出基于DSP的步进电机驱动器设计方案。通过采用最大电流/转矩的转子磁场定向失量控制,完成对两相混合式步进电机的控制。硬件采用TMS320FS2812为电机控制器,设计了电流采样电路、电机功率驱动电路及相关的辅助电路。在逆变电路中采用SVPWM调制策略,提高电机控制性能。并对驱动器的输出进行测试实验,得出对电机的控制越是细分,电机的控制性能越好。To improve the steady-state performance and dynamic characteristics of the two-phase hybrid stepping motor based on the purpose of this paper,combined with the torque vector control strategy,proposed DSP stepper motor driver design based on. By using the maximum current rotor field orientation torque vector control, to control the two-phase hybrid stepping motor. The hardware adopts TMS320 FS2812 the design of the motor controller,current sampling circuit,motor driving circuit and auxiliary circuit related. The SVPWM modulation strategy in the inverter circuit,and improve the performance of motor control. The output of the drive test,the control of motor control is more segmentation,better performance of the motor.
