Abstract: A novel algorithm call Generalized Predictive Control (GPC) is shown to be particularly effective for the selftuning control of industrial processes. The method uses longrange predictive control (LRPC) ideas with a carefullychosen CARIMA plant model and various `horizons'' which allow the choice of a rich variety of control objectives.
Hydraulic gap control of rolling mill based on selftuning fuzzy PID ... test results of the step response and the position tracking that is carried out on the HGC system of a cold rolling mill show that when compared with the conventional PID control system, the selftuning fuzzy PID system has the characteristics of fast response, short rise ...
In this paper, the soft MPC is tested in a real cement mill and compared with that of the existing high level controller based on the fuzzy logic principle. The main difference in controlling the cement mill in the CEMulator and the real plant is that the CEMulator has uncertainty and noise defined by IFAC DYCOPS 2013 December 1820, 2013.

Jul 01, 2019· In this study, a fuzzy logic selftuning PID controller based on an improved disturbance observer is designed for control of the ball mill grinding circuit. The ball mill grinding circuit has vast applications in the mining, metallurgy, chemistry, pharmacy, and research laboratories; however, this system has some challenges.
a closed grinding circuit system in the cement industry. A Markov chain model is used to characterize the cement grinding circuit by modeling the ball mill and the centrifugal dust separator. The probability matrices of the Markovian model are obtained through a combination of comminution principles and experimental data obtained from the parti
