Abstract :
This paper discussed the control performance improvement with PDF (Pseudo Derivative Feedback) Control in Electro-Hydraulic Servo System, especially in system performance analyses in robustness, control accuracy and, extending system bandwidth, etc. It indicates that PDF control for electro-hydraulic servo system possesses better control performance than traditional PID based control strategies, especially in the robustness characteristics and frequency response feature. The study and experiment results show that the PDF control can provide better comprehensive performance in hydraulic servo system.
