Velocity Control of Hydraulic Servo System with Heavy Load and Large Capacitya

대부하 대용량 유압 서보 시스템의 속도제어

The velocity control of hydraulic servo system with heavy load and large capacity was investigated through the linear analysis and digital computer simulation. Each part of the nonlinear hydraulic servo system was mathmatically modelled. The result of linear analysis and computer simulation showed that the use of derivative of load pressure as a feedback signal is effective in velocity control.
