Investigation of Control of Speed of Diesel Engines Using PID Governor 2000-01-0264

The paper presents the speed control analysis for a turbocharged engine by simulation using block diagram type of modeling and solving the differential equations using both fourth order Runge-Kutta and transfer function methods using various combinations of proportional, integral and differential coefficients in a PID controller with application of various types of oscillating loads.
The simulation results show that the governor using PID control provides the best control of engine speed and the optimum values of these coefficients are different for different operating conditions having different amplitude and frequency of load fluctuations. The Runge-Kutta method is found to give more accurate results but takes more computer time.
