The mathematical model of diesel engine and its speed regulation system are presented and computer simulation is conducted in Matlab software. Simulation results verify that the proposed method improves the control accuracy of speed of diesel engine. A fuzzy PID hybrid controller and a Genetic Algorithm PID of parameter self-adjusting is put forward in this paper.
