UPS inverter의 2차 데드비트 응답을 위한 반복부하예측기법

Repetitive Load Prediction for Second Order Deadbeat Response Applied to UPS Inverter

Repetitive Load Prediction is proposed for the UPS inverter application of the second order deadbeat controller which is robust against the calculation time delay and the parameter variation and which gets fast response against the load variation. The proposed technique predicts the load current ahead of two sampling time using that the load current is periodic. This is effective under nonlinear load condition. The proposed technique is derived theoretically and verified through simulation and experimental result.
