Abstract :
An electric car and teeterboard self-balanced system was designed in this paper. The 32-bit ARM chip LPC2138 was applied as the MCU and the stepper motor was used as the driven device for the electric car. The angle signals derived from the AccuStar electronic inclinometer by moving average digital filter helped to accomplish the closed loop digital PID control system and keep the balance of the teeterboard under different conditions. The experiment results show high control precision and quick response.
