热连轧板宽板厚的实用自抗扰解耦控制
A practical decoupling control solution for hot strip width and gauge regulation based on active disturbance rejection
摘要
Abstract
To deal with the strong interactions between loops,large time-delay and random uncertainties in the multivariable system of the hot rolling mill,we propose a solution of active disturbance-rejection control (ADRC).In this solution,a time-delay unit is added before the conventional reduced-order extended-state observer.For the fair comparison of the proposed ADRC and the conventional PID controller,parameters of each algorithm are obtained by using the mutative-scale chaotic optimization method.Simulation results show that the optimized ADRC not only has better decoupling performance,but also provides higher robustness and adaptability against the model-parameter uncertainties and external disturbances.关键词
