High-precision Controller for Stepper Motor with Auto Speed Regulation Based on FPGA

Considering the shortcoming of existing stepper motor controllers,a FPGA-based high-precision controller for stepper motor was proposed to regulate the motor speed automatically,in which,its host MCU can set parameters including the working distance,speed,starting speed and deceleration distance as desired.The application results show that this controller can accomplish the control on speed and position of the stepper motor automatically.
