Fuzzy PID Model -Based Study on Idle Control of Gas Engine
Fuzzy PID Model -Based Study on Idle Control of Gas Engine is a scholarly work, published in 2014 in ''Open Cybernetics and Systemics Journal''. The main subjects of the publication include fuzzy logic, computer science, electric vehicle, hydraulic machine, idle, PID controler, control in organization management, vehicle dynamics, and control theory. Nowadays, natural gas conforms to the conditions of environmental protection and renewable energy, which plays a significant role in the future development of mankind.It has made some progress in applying natural gas to the automotive industry.As authors all know that the source power of automobile comes from engine, therefore, based on the study on the control algorithm of gas engine, this paper aims to provide theoretical basis for further application of gas engine.This paper analyzed PID control algorithm, fuzzy control algorithm and fuzzy PID control algorithm, designed corresponding controllers based on the algorithm principles, applied these three algorithms to the idle control process of the automobile gas engine.This paper concluded that the fuzzy PID control algorithm is of higher superiority through contrastive analysis on the control effects of theses three algorithm in the process of cooling high idle start, switching high idle to low idle and switching low idle to high idle.
