Experimental study on speed control of main diesel engine

摘要

This paper describes experimental study on the speed control of the main diesel engine through a direct digital control (DDC) system. The used control method is due to the classical technique based on the PID control law. In particular, in this case we emphasis on the control technique using the new signal, that is, the torque signal gained from the propeller shaft. In order to contradict effect of the torque change, we introduce a control method on the basis of the DDC system. Finally, our method is proved to be very useful method by illustrating the experimental results.
