Abstract

PURPOSE: To control the speed of working machine by simple structure, by providing a clutch in a control system for the working machine and controlling the clutch on or off.
CONSTITUTION: When the working machine 1 is in a position S1 different from a command postiton So, a position detector 2 produces a signal es1 corresponding to the position S1. A set signal Eso corresponding to the command position So is applied to an addition point 9. A difference signal e is applied to an amplifier 3 and a speed control circuit 6. A comparator 5 produces a signal Ec to turn on the clutch. A speed control circuit 6 produces a set speed signal Ev, which is applied to an sctuator 4. The actuator 4 drives the working machine 1 at a set speed V by the signal Ev. When the working machine 1 approaches the command position and the difference signal falls, the output signal Ec of the comparator 5 become zero and the clutch 7 is turned off. Thereby, the actuator 8 is disconnected from the working machine 1, and the machine 1 stops in the command position
