Study of Alumina Concentration Control Based on Intelligent Characteristic Model
In electrolytic aluminum production processing, the measurement and control of alumina concentration is one of the three most important control aims. However, due to alumina concentration can not be measured directly and continuously online, and electrolytic aluminum production process is nonlinear, time-varying and large delay, which can not be described through the mathematical analysis model. Therefore, efficient and reliable development of alumina concentration control method is very important. In view of the above problems, alumina concentration is controlled by intelligent characteristic model and single neural adaptive PID controller, which achieve a good control effect.
