Patent ID: 8805569

Claim:
A controller comprising: a driving device which drives equipment and causes the equipment to perform mechanical work; a computation element which computes a target value related to an action of the equipment; an automatic controller which outputs an automatic control signal for the driving device based on a target value computed by the computation element so that the action of the equipment becomes stable in a desired condition; a manual intervention unit which is operated to correct, manually, the action of the equipment; a manual intervention control unit which outputs a manual correction signal for the driving device in response to an operation performed for the manual intervention unit; and a manual correction unit which makes a determination as to whether there is an overcorrection due to a manual operation based on an automatic control signal output from the automatic controller and a manual correction signal output from the manual intervention control unit, and outputs, to the driving device, a product obtained by multiplying a manual correction signal output from the manual intervention control unit by a first prescribed gain regulation value.
