The Application Research of Fuzzy PID on Oil Low-Consuming System

Article Preview

Abstract:

In accordance with the phenomenon of 0# diesel be cannot used in winter of northern china, put forward the low consum-ing fuel system that diesel is heated to the set temperature in oil depot, for locomotive use 0# diesel fuel. heat exchanger as the control object in the system,firstly, the mathematical model of the heat exchanger is established.secondly, the transfer function using system recognition is getted.thirdly, the fuzzy PID controller is designed and simulation was done. the simulation curve was analyzed. Finally the conclusion is presented, which the fuzzy PID in this system is better than the traditional PID.
