The Development of Flying Touch Hot Rolling Control Method Based on SMCSPO
2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)(2016)
摘要
To produce good quality of steel plates, scratches on steel plate should be minimized in hot rolling process. The new method, flying touch algorithm is introduced to control the gap between upper and lower roller for reducing scratches. In the flying touch method, the uniformity of coil can be debased due to variation of reaction force between rollers and steel plate. Therefore, the robust control algorithm and force estimation method is needed to apply flying touch method to hot rolling process. This paper introduces sliding mode control with sliding perturbation observer (SMCSPO) in flying touch hot rolling process. This paper also survey the effect of improved smoothen curve trajectory for realizing the flying touch and velocity synchronization on rolling mills' roller to reduce a scratch due to a friction force caused by the velocity desynchronization.
