英文摘要： Aim at typical industrial processes with unstable operative conditions, and strong disturbances, the project studies methodology on dynamical modeling and control for processes with performance estimation, in which dynamical modeling, adaptive fuzzy control, and performance estimation for control system are investigated based on real-time data. The project studies modeling method combining association analysis and data-driven modeling, in order to establish a sintering bum-through point (BTP) model with subspace modeling based on principal component analysis. Such model will serve as reference model, by which a modeling reference adaptive fuzzy control method based on the differential evolution algorithm is studied in order to realize intelligent control for BTP. With real-time performance of control taken account, a performance estimation method for process model with data-driven subspace modeling and adaptive fuzzy control is studied, in which the comprehensive performance will be assessed by using expert analyzing method. Thus based on this estimation method, the project studies an on-line coordination optimization strategy for adjusting parameters of process model and controller, so that the system will be controlled stably, and good at adapting different operative conditions. This method will be testified i
