Fuzzy PID based automobile cruise control system

Abstract

The invention provides a fuzzy PID based automobile cruise control system which comprises an automobile cruise control system module, a fuzzy control module, a traditional PID module, a fuzzy PID controller design module and an MATLAB simulation result module, and the modules are connected via electric signals. According to the invention, overshoot of the automobile cruise control system is correspondingly reduced, reaction speed is increased, the driving speed is effectively kept at the cruise speed, an accurate mathematical model is not relied on, the system is not sensitive to parameter change, and the robustness is very high.

Description

technical field [0001] The present invention relates to a control system, particularly a kind of PID controller (also known as a PID regulator) based on fuzzy PID (in process control, controlled by the proportion (P), integral (I) and differential (D) of the deviation. The most widely used automatic controller) car cruise control system. Background technique [0002] The automobile cruise control system (CCS) has been developed for more than 30 years. It has gone through four stages: mechanical control, transistor control, analog microcomputer control and digital microcomputer control. Because domestic research on automobile cruise control starts late, and the technology is relatively backward, the domestic research and application of automobile cruise control system is mainly based on single-vehicle constant speed control. Although some domestic institutions have started research on electronic cruise control devices, generally speaking, domestic research on automobile crui...
