摘要: Abstract This paper is concerned with the problem of roll eccentricity compensation in steel strip rolling mills. A new sensor proposed for task retrieving desired reference signal from available force measurement. The implements a modified comb filter structure which can be arranged either tunable or adaptive form. consists number second-order infinite impulse response notch modules. Error surface analysis carried out filter. Results this confirms that convergence guaranteed provided initial frequency estimate selected within unimodal region. Such condition easily satisfied practice since fundamental related to speed. Simulation results based on typical experimental data clearly indicate appropriate and offers distinct advantages over other methods. final compensator functional units making up complete system are discussed some detail paper.
