Abstract
According to the Seventh Freescale Cup Intelligent Vehicle Contest, through in-depth study of modeling the two wheel self-balancing intelligent vehicle system, Kalman filter algorithm, and the control algorithm of the electromagnetic guided two wheel self-balancing intelligent vehicle， modeling the electromagnetic guided two wheel self-balancing intelligent vehicle system, and Kalman filter algorithm is applied to the two wheel self-balancing intelligent vehicle in the measurement of car angle. In order to improve the response speed of the motor of car model and control accuracy, the motor inner control is applied to the system. According to the mathematical model of the system and the Kalman filter model, Kalman filter algorithm for the intelligent vehicle system, motor inner loop control algorithm and the whole system is simulated by matlab. Finally, the design of the algorithm is testified in the actual experiment platform to verify its effectiveness. The result shows that the performance of the system is good, the design of the algorithm significantly improve the operational characteristics of the electromagnetic guided two wheel self-balancing intelligent vehicle, and verified the correctness of the established mathematical model of the system and the Kalman filter model.
