- Abstract
A design of a circuit controlling stepper motors in light-shifting device of the satellite-born spectrometer was proposed. This design utilizes FPGA as the core control chip and LMD18200 as the driving chip of stepper motors. To reduce the abrasion of bearings and overcome the increase of the resistance in orbit operation, a function that the rotation speed and the driving torque are able to be adjusted is added into this design. PWM control is implemented to adjust driving torque. The real tests verified that the design's range of controlling driving torque and rotation speed match the requests of the spectrometer.
