PID 제어를 이용한 Switched Reluctance Generator의 출력 전압 제어

A SRG (Switched Reluctance Generator) has many advantages such as efficiency, simple controllability, low cost and robustness compared with other machines. But the theories that have been adopted as SRG control methods up to the present are complicated. This paper proposes a simple control method using PID, which controls only a turn-off angle while making turn-on angle signals of SRG constant Controlling the voltage differences between the reference and the real value and calculating the proper turn-off angle for the load variations can implement to keep the output voltage constant The control method suggested in this paper enhances the efficiency of this system and simplifies the hardware and software by using only the voltage and speed sensors. The proposed method is verified by experiment
