Abstract
A small intelligent car system based on MCU SPCE061A and MCU 89S52 was introduced. Firstly, CCD camera was used as its path recognition device to extract path information through image recognition. Based on fuzzy strategy and the least square method, two-dimensional information involving gear angle between the car and the path was measured. Then fuzzy PD controller was implemented based on MCU, which can guarantee to track accurately. Finally, experiment results are given to demonstrate that the designed system can track random path at smooth speed, and the overall system is stable and accurate.
