基于PID控制算法的气味循迹车设计

PID control algorithm based on odor tracking car design

气味源的循迹是目前的研究热点之一,在以后的日常生活以及生产方面有着较为广泛的运用。本文介绍了一种基于STC12C5A60S2单片机设计的简便智能气味循迹小车。采用两个气味传感器,根据浓度差判断气味流向,并通过PID算法控制舵机打出偏角,使小车循着气味行走。整个硬件模块的设计结构简单灵活,通过实验仿真,在室内时变气流场的环境下,该小车能达到气味循迹要求。

Tracking the source of the odor is currently one of the hot, has a more widely used in everyday life and future production. This article describes a simple and intelligent tracking car smell STC12CSA60S2 chip design is based. Using two odor sensors to determine the concentration difference between the smell of the flow, and played by the PID algorithm control steering angle, so that the car follow the smell of walking. Simple structure of the entire hardware module design flexibility, through simulation experiments, the time-varying flow field indoor environment, the car can reach odor tracking requirements.
