Abstract

Smith predictor is presented for monitor finishing automatic width control (M-FAWC) system to deal with the large transport time-delay. With the minimal settling time with a constraint, the optimal parameters of Smith predictor are tuned based on the mutative scale chaos optimization method to meet high performance of strip width. The simulation results of the M-FAWC system show that the optimized Smith predictor has better dynamic performance than the conventional PID controller, and the chaos optimization algorithm is effective.
