Title Design and Implementation of Smart Car for the 8th Freescale Cup——Research and Design of Control
AlgorithmBased on 32-bit MCU for Car Guided by Photoelectric
Abstract According to the 8th "freescale" cup national undergraduate smart car competition, modeling, the kalman filtering algorithm and control algorithm is studied for the self-balancing intelligence vehicle system of two rounds guided by photoelectric in detail. Meanwhile, the model for the intelligence vehicle system is built, and the kalman filtering is adapted to the measurement of vehicle gesture. To improve the response speed and control precision of the motor, the inner control is designed. Combining mathematical model of system and the kalman filter model, kalman filtering algorithm, inner control and the whole system control are simulated in matlab. Finally, the algorithm is applied into the actual test to test its effectiveness. Actual debugging results show that the system performance is good, the running characteristics of the self-balancing intelligence vehicle of two rounds guided by photoelectric system receive a significant boost, and the correctness of the established mathematical model system and the kalman filter model are verified.
