Abstract

PURPOSE: To prevent the production of a shock at a starting stage, by previously deviating a control instruction so as an object to be controlled can not move from a present position, and by restoring a control system composition of a normal connection after retruning the object to the required position as a result of reducing the deviation volume.
CONSTITUTION: When turning on a power source, contacts 17 and 21 are closed. As an output Xa of an integrator 15 is supplied to a deviation reduction circuit 26 at that time, a control output U of a controller 1 changes toward 0. If the contact 17 is opened when the control output U becoms 0, a contact 18 is closed and a closing loop of the controller 1 is formed. If the deviation signal Xa is positive, a contact 19 is closed and and accelerating signal X"a is applied so that the deviation signal Xa can be reduced. When the deviation signal becomes 0.5 times as much as its initial value, the contact 19 is opened, and simultaneously a contact 20 is closed and a reduction signal -X" is applied. When the deviation signal Xa becomes 0, the contacts 20 and 21 are opened.
