Abstract
PURPOSE: To provide an acceleration/deacceleration control system of hydraulic actuator and a speed control unit which controls a set speed of hydraulic actuator by rate of inertia load value in order to stabilize car body at starting or stopping period of hydraulic cylinder.
CONSTITUTION: Operation system 10 sets speed of hydraulic cylinder 4, a set value of which feeds an operation signal x1 from the signal generator 11. Further, inertial load detecting unit 12 detects a load value of inertia load 7 to feed a detecting signal L. Acceleration/deacceleration codntrol unit 13 enters into an operation signal x1 and a detecting signal L, reducing acceleration speed of hydraulic cylinder 4 when L is large feeding, a signal x2 to increase acceleration speed when L is small, flow control unit 14 entering a signal x2, and this enabling hydraulic oil flow proportional to a signal x2 to supply to hydraulic cylinder 4.
