High performance hydraulic pump system using switched reluctance drive

High performance hydraulic pump system using SR drive 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. At last the proposed hydraulic oil pump system is verified by computer simulation and experimental results.
