Application Analysis of the Fuel Viscosity and Temperature Control System Based on the Sliding Mode Theory

摘要

With the shortage of the petroleum resources day by day,the fuel oil price is becoming higher and higher.The ship companies want to use the heavy diesel oil and inferior fuel with lower price for the marine diesel.Temperature is a variable with great inertia.Using the PID control algorithm,which will lead to the consequence of over correction in the controlling process,the advantage of sliding mode variable structure control is the small over correction.In this paper,based on thermodynamics and heat transfer theory,the mathematical model of temperature control system is built,the sliding mode movement equation and the sliding mode variable structure controller is obtained.This makes the application of temperature control take the advantage of sliding mode variable structure control.
