Tuning of PID controller for diesel engines using genetic algorithm

The engine speed controller of a conventional diesel engine is called a Governor. In order to control engine speed, the governor controls the amount of fuel using fuel rack. The paper establishes a mathematical model to describe the rotation speed regulation process on diesel engine. The mathematical model of D6114 diesel engine system controller has been established for control and analysis, a flexible and fast tuning method based on genetic algorithm technique tuning with different population size and generations number to determine the optimal values of the PID controller parameters to improve the transient response of the system.
