The system uses msp430f5438 microcontroller as the master chip, L298N driver stage to drive the stepper motor module using the mode switch button, through the measurement precision potentiometers, the stepper motor control. In software, the free pendulum angle and number of steps of the stepper motor to establish a correspondence between using fuzzy control algorithm and PID control algorithm, the stepper motor to get more precise control.
