Design And Research Of The Ship Main Engine Lube Oil Temperature Intelligent Control System

The main engine lube oil is very important for the stability work of the diesel engine. It is advantageous to exaltation diesel engine of motive and to some extent can decrease the fuel consume quantity and waste gas of creation if we can control the lube oil on a well temperature. The parameter of ships lube oil system was direct reflect the effect of the motive system lubricate, It is the duty for the main lube oil system to keep the important parameter in the right scale. If the main lube oil temperature mode can works well or not can directly refer to the effect of the lubricating. It can severity influence the economy, motive and safety of the main force system.Currently control methods of ships lube oil temperature system mostly choose normal regulations PID, but tradition lube oil temperature control system with unline,time change and big delay characteristics.It is a back track shut wreath system. So tradition methods of PID control can't reach the satisfacory effect.The temperature of the ships diesel engine lube oil usually appear super adjust, respond to speed slow, temperature control unclear and It can influence the function and life of the ships diesel engine.Textual purpose is to research the forerunner control technique to replace normal regulations control, It can precision adjust the temperature of the diesel engine lube oil.This text first introduction the work principle of the ship lube oil temperature control system and the project of the intelligence lube oil temperature control system.Analysis mathematics model of main lube oil temperature control system, and make use of Matlab Simulink mode establishment the imitate system. Then researching the forerunner PID control technique of the lube oil temperature control system, It is the first time take the nerve network PID control to them. Imitating the nerve network of the system PID control with the Matlab.Ansys and solve the problem with understanding method.The result of the imitate and the experiment express that the never net PID control with speed quick, control accuracy,small lube oil temperature adjustand it has good control effect.
