FPGA Based Optimal Position Control For Flying Shear In Hot Rolling Mills

摘要

The increasing need to save energy and minimize scrap together with requirements on the accuracy and quality of cutting operations in continuous rolling mills have necessitated the development of a concept of flying shear control. Sophisticated position control algorithms based on optimal positioning with a moving target are described. Effort to replace the existing higher end and high cost real time controllers by the state of the art high performance, economical FPGA _ based industrial controllers. This controller will be flexible for engineering a specific real time application with limited inputs and outputs rather than being part of a large automation system. Theoretical considerations are supported by digital simulation and verify the validity of the concept. The implemented flying shear control system proved highly efficient in operation.
