A kind of closed hydraulic loop based on variable frequency speed regulation was designed,through PLC control the inverter to control the hydraulic system.The traditional PID control and the pseudo derivative feedback control were used for the system.LabVIEW interface was built to observe the response.The results show that using the pseudo derivative feedback control can improve dynamic characteristics and robustness.
