本发明涉及种电解铝炭素阳极熟料的回转窑煅烧过程综合协调控制方法及系统，属于自动控制技术领域，根据窑皮温度和窑内温度的非线性传热关系，按照神经网络和有限元的混合建模方法，根据窑皮温度、窑头温度、窑尾温度，以及窑头、窑尾压力等工艺检测参数，建立窑皮温度与窑内温度的非线性映射关系，以克服现有技术存在的煅烧带温度的测量粗糙，不能真实反映的煅烧带温度、位置、长度数据的问题；同时在现有回转窑自动控制的基础上，加入种高效、稳定、实时的网络通信方案，以实现信息、操作管理集中化和控制分散化，从而达到提高产品质量、节能降耗、可靠稳定运行的目标。 The invention relates to a comprehensive coordination control method and system for a rotary kiln during calcining of clinker of an electrolytic aluminium carbon anode, and belongs to the automatic control technology field. Through a neural network and finite element mixed modeling method, a nonlinear mapping relation between a kiln coating temperature and a temperature inside a kiln is established on the basis of a nonlinear heat transfer relation between the kiln coating temperature and the temperature inside the kiln according to technical detection parameters such as the kiln coating temperature, a kiln head temperature, a kiln tail temperature, the kiln head pressure and the kiln tail pressure. In this way, the problems of the prior art that t
