Intelligent control research based on the smart car

This paper uses a “smart car” as the platform for intelligent control research. MC9S12DG128 is chosen to be the main control unit, which is produced by Freescale Semiconductor. A smallest intelligent control system is designed in this paper and it implements smart car's self-tracking driving using path identification algorithm. In this paper, the intelligent control study of the smart car includes: the extraction of path information, self-tracking algorithm implementation and direction and speed control. The implementation of different modules of this system is introduced respectively. The highlight is the process of smart car intelligent control: the open-loop control and closed-loop control applications including incremental PID control algorithm and BangBang control algorithms. At last but not the least, the smart based on intelligent control system has been tested.
