摘 要: 介绍了AT89C2051单片机的性能及特点,分析了巡航控制系统(CCS)的基本原理和结构特点,确定了输入输出信号后,搭建了巡航模拟实验台,提出了一种新型巡航控制系统设计方案,即对转速、节气门开度双闭环控制,以模糊PID作为控制算法,改善控制效果。并且自做了实验台。通过实验结果分析,证实了所设计巡航控制系统的合理性和实用性。 Function and characteristic having introduced the AT89C2051 monolithic machines, After analyzing the basic principle and structure traits of Auto Cruise Control System (CCS)and defining input signals and output signals,A CCS simulant equipment was buih up, We brought forward a kind of new control scheme which is that Dual closed--loop controlling method of auto speed and throttle threshold is adopted and controlling arithmetic is parameter adaptive PID. the controlling elect is improved.And from has made the laboratory bench .By an alysis of experimental results,it is confirmed that thecruise control system designed is rational and practical.
