Abstract
To overcome the problem of traditional PID control of diesel engine,a fuzzy controller for diesel en- gine has been designed based on the fuzzy control theory,with the established simulation system of diesel en- gine,the simulation of the diesel engine dynamic process of free acceleration under the fuzzy controller has been conducted,and then the dynamic change performance of engine speed,torque and fuel quality has been compared and analyzed with those performance of the engine under PID controller.The results prove that com- pared with PID control,fuzzy control can be used to solve the problem of the complicated control of diesel en- gine.
