Self-tuning fuzzy looper control for rolling mills
Farrokh Janabi‐Sharifi, J. Fan · 2002
Deals with the problem of looper control for tension-free rolling. Conventional controllers can not deal effectively with unmodeled dynamics and large variations which can lead to scrap runs and damages to machinery. Therefore, a fuzzy controller has been designed to use the expert knowledge of the operators for disturbed process control. Also, a self-tuning algorithm is incorporated for both on-line and off-line tuning of the fuzzy membership functions. The paper discusses the design of the fuzzy logic controller and its self-tuning. The effects of various design options are discussed and practical conclusions are made. Results from simulations are also presented.
