摘　　要：本系统拟计划采用DSP控制步进电机推动轻装置移动实现测量装置的精准定位。系统拟采用的主控制器为DSP28335,被控对象为最小步进角为1.8°的42步进电机,采用DSP输出PWM脉冲波通过电机驱动器控制电机的运行。系统根据具体控制要求改变对PWM参数的设置,并通过相关的算法对过程参数进行修正以完成系统目的。电机控制系统的控制精度为线位移10μm,能够达到为实验室项目进行支持的目的,本系统亦可广泛应用于电机控制领域。This system intends to precisely position a measuring device by using DSP to control stepper motor driving the moving unit. The DSP28335 is used as the master controller in system, the controlled object is a 42 stepping motor with a minimum step angle of 1.8 °, the running of the motor is controlled by the PWM pulse output from DSP through motor drive controller. According to the specific requirements, the PWM parameter settings are changed, and the relative algorithm is used to modify the process parameters so as to achieve the purpose of the system. The control precision of the motor control system is 10μm linear displacement, achieves the purpose of supporting a laboratory project, the system can also be applied to a wide range of motor control.
