Abstract: The advanced HMFFT and A-WAVELET roll eccentricity control algorithms were studied. Then based on the four hydraulic roll mill of the laboratory, the experiment of the advanced roll eccentricity control scheme used HMFFT and A-WAVELET algorithm was made. An effective roll eccentricity phase detection and control scheme was presented. The two-level control system of roll eccentricity was established, and the relevant program was designed and debugged. The results showed that the effect of experiment is very good, so the two-level eccentrcity control system is a full scheme to solve the problem of roll eccentricity and is valuable for application.
