적응 슬라이딩 모드 관측기를 이용한 Switched Reluctance Generator의 위치 센서 없는 구동에 관한 연구

초록

The position information of the rotor are required while the SRG(Switched Reluctance Generator) is drived. The position information is generally provided by shaft encoder or resolver. But it is weak in the dusty, high temperator and EMI environment. Therefore, the sensor is able to required to eliminated from the SRG. In this paper, a estimation algorithm for the rotor position of the SRG is introducted and a constant DC-link voltage is controled by PID controller. The estimation algorithm is imple- -mened by the adaptive sliding observer and that it is able to estimate the rotor position well is proved by the simulation.
