Electric governors are widely used in diesel engine applications. And a proportional, integral and derivative(PED) controllers runs the electric governor in order to control the engine speed. However, it is difficult to analyze the system stability due to the non-linear characteristics of the diesel engine, and as a result, the PID controller should be(More)
A variable-speed engine generator set for an isolated power system is investigated due to reduced fuel consumption and less emission. However, because of the sluggish dynamic behavior of the internal combustion engine, the power quality would be degraded during the sudden load power surge, where the power required by the load is not available by the engine(More)
