摘　　要：针对闵行发电厂11号炉中储式钢球磨制粉系统的特点,以多变量控制理论、模糊控制理论及自适应优化理论为基础,在充分考虑了制粉系统特点后,以及针对不同被控过程的具体特性,提出了基于不同控制理论的实用控制策略和功能相对独立的控制子系统,再通过对各控制子系统的集成,完成了整个制粉系统的全工况优化控制。所提出的控制方法自2003年3月成功地应用于闵行电厂11号炉的制粉系统控制中,不仅确保了该制粉系统的长期可靠运行,而且使制粉系统工作在最佳工况,取得了明显的经济效益。Taking account of the specific features of the ball-mill-based bin and feeder system of No.11 boiler at Minhang Power Plant and on the basis of the multivariable control theory,fuzzy control and self-adaptive optimization theory with due consideration of characteristics of the mill system,presented were the practical control tactics based on different control theories and control sub-systems incorporating relatively independent functions.The foregoing was proposed after having taken into account the concrete peculiarities of different controlled processes.Then,through an integration of various control sub-systems,a full-load optimized control of the whole mill system was accomplished.The control method proposed by the authors has been successfully used in the control of the mill system of No.11 boiler at Minhang Power Plant since Mar.2003,thereby not only ensuring a long-term and reliable operation of the mill system but also enabling it to work at its optimum operating condition with notable economic benefits being attained.
