  • Control Of Position Or Direction (AREA)

Abstract

PURPOSE: To ensure an extremely high-accuracy positioning even with the effect of disturbance given during the control, by detecting the fact that the control subject enters the prescribed error range and then delivering again the position set value to give the same stop control.
CONSTITUTION: The signal 1 delivered from the output terminal 0 of the sequence counter 1 is applied to the position setting device 2 via the OR circuit OR1 and in the initial state before the control of positioning of the control subject 5. The device 2 delivers the previous set position command signal ES with application of the signal 1. On the other hand, the position detector 6 detects the present position of the subject 5 and then delivers the corresponding position signal ES. Then the driving circuit 3 drives the actuator 4 in response to the deviation signal S of the signals ES and eS, thus carrying out a position control of the subject 5 such as a hydraulic cylinder or the like. In sucy way, the fact that the subject 5 enters the prescribed error range is detected and then the position set value is delivered again to perform the same stop control. As a result, an extremely high-accuracy control is possible for positioning even with the effect of disturbance.
