Abstract :
A new vibration suppressing approach CCHFLO (compensative control based on Hinfin filter and load observer) for rolling mill drive system is proposed under analysis of two-loops two-mass electrometrical model and engineering practice. Besides the conventional load observer loop, a pseudo roller speed state feedback is added by means of the roller speed observer which is the Hinfin, filter constructed by solving the EVP problem of LMI. Compared with the conventional state observer and the load observer method, it looses the suppose condition as well as constructs the pseudo full state feedback. Simulation results indicate that the proposed method can achieve better vibration attenuation effect on both motor and roller
