| Abstract: | 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. |
