Pressure Control Drive of SRM for Hydraulic Pump with Pressure Predict Method and Direct Torque Control Method

압력예측기법과 직접순시토크제어기법을 통한 유압펌프용 SRM의 압력제어구동

Direct Instantaneous Pressure Control(DIPC) method of SRM using pressure predict method is presented in this paper. A hydraulic pump system has an inherent defect that its dynamic behavior causes by interaction between the sensor and hydraulic load. It will make sometimes the whole system become oscillatory and unstable. Proposed system integrates direct instantaneous torque control (DITC) and Smith predictor to improve dynamic performance and stabilization. The proposed hydraulic oil pump system is verified by computer simulation and experimental results.
