CONTROLLER AND CONTROLLER FOR ROLLING MILL

WIPO Patent Application WO/2011/033615

A1

Provided is a controller, wherein an overcorrection is limited when a manual intervention is implemented for the motion control of a device so as to be able to stably control the motion of the device in a desired state. The controller is provided with a drive unit for driving a predetermined device to have the device perform mechanical work, a calculation element which derives a target value associated with the motion of the device, and an automatic controller for outputting an automatic control signal to the drive unit in such a manner that the motion of the device is stabilized in a desired state according to the target value. In addition, the controller is further provided with a manual intervention controller for outputting a manual correction signal to the drive unit in response to an operation performed on a manual intervention device. Furthermore, the controller determines whether or not there is an overcorrection by a manual operation, according to the automatic control signal and the manual correction signal, multiplies the manual correction signal outputted from the manual intervention controller by a predetermined gain control value, and outputs the signal to the drive unit.
