The excitation control of a synchronous generator using proportional, integral, and derivative (PID) control is considered. The proposed PID power system stabilizer uses the generator frequency and voltage deviations to provide a supplementary signal for the excitation control. The gains of the PIC controller are calculated for complete pole placement. Digital simulation of synchronous machine subject to a disturbance is performed to demonstrate the effectiveness of the proposed controller. It is found that the proposed PID stabilizer outperforms the traditional power system stabilizer currently used by most power plants.<<ETX>>
