用于智能车速度控制的PID程序设计

Design of PID Program Used for Controlling the Speed of intelligent Vehicle

由于小车在行进过程中路况复杂,还要保持高速,稳定,很具有挑战性。设计了一种基于单片机的智能车,其中速度量控制采用了PID程序设计。所以采用闭环控制是必要的选择。硬件方面给小车提供的测速装置为小车的闭环系统提供了必要的基础。在PID控制中进行了比例,微分,积分调节,实现了小车的高速行进。

Due to the complexity of road during the vehicle travelling on the road, it is challengeable to keep the vehicle stable and in high speed. A PID program used for controlling the speed of intelligent vehicle based on a single chip microcomputer has been designed. It is necessary to adopt closed-loop control. The tachymeter of the vehicle provides a hardware foundation for the closed-loop system. We have designed the PID program by adopting the classic PID control meanwhile implementing proportion, differential and integral processes, thus ensuring the vehicle travelling in high speed.
