Abstract

PURPOSE: To eliminate overshooting and hunting and to shorten a controlling time, by bringing an instruction position gradually closer to a final target position from a position before control-starting.
CONSTITUTION: A movement set signal e2 joining in a switch circuit 5 is input to a primary delay element 6 as a result of a control start instruction signal S1 being generated. A sample hole circuit 4 holds a detecting signal e1 from a cylinder stroke detector 2, i.e., a position of an object to be controlled before control-starting. An adding amplifier 7 adds a set signal from the primary delay element 6 and a signal from the sample hold circuit 4. An adding point 3 produces a deviation between the position detecting signal e1 of the object to be controlled and a position instruction signal e20, and the deviation e3 is added to a compensator 8. The deviation signal e3 is used as a signal which instructs a moving speed of a cylinder 1 of a working machine, i.e., a movement speed of the object to be controlled.
