Title:
CRUSHER CRUSHING LOAD CONTROL DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/092092
Kind Code:
A1
Abstract:
This crusher crushing load control device comprises: a load response acquisition unit for acquiring, as an unprocessed load response, a load response obtained as a response for a given command value outputted with respect to a given control subject of a crusher; a pre-processing unit for pre-processing the unprocessed load response to obtain a load response; a feedback control unit for generating a new command value on the basis of the deviation between the load response and a prescribed target load value; and a control parameter adjustment unit for adjusting a control parameter of the feedback control unit on the basis of the load response. The pre-processing unit has a steady-state characteristic extraction filter for attenuating a crushing oscillation unique to the crusher that is included in the unprocessed load response.
