Title:
CONTROL METHOD AND APPARATUS FOR ROLLER PRESS, AND ROLLER PRESS
Document Type and Number:
WIPO Patent Application WO/2023/066093
Kind Code:
A1
Abstract:
The present application discloses a control method and apparatus for a roller press, and a roller press. The method comprises: by means of a Smith predictor, obtaining a first roller gap correction amount of a roller press under feedback delay; obtaining a second roll gap correction amount associated with a feedback thickness, the feedback thickness being the thickness of a battery electrode plate after being rolled by the roller press; on the basis of the first roller gap correction amount and the second roller gap correction amount, determining a total roller gap correction amount of the roller press; and adjusting a pressing roller gap of the roller press by means of the total roller gap correction amount. In the control method for a roller press of the embodiments of the present application, the roller gap correction amount of a roller press under a feedback delay may be obtained by means of a Smith predictor, the roller gap correction amount fed back by a thickness gauge is corrected, and the thickness fluctuation caused by feedback lag is reduced, thereby reducing the deviation of the rolling thickness of a roller press, and thus improving the yield rate in battery production.
