A sintering temperature detection and control method of alumina rotary kiln based on fuzzy data fusion

An algorithm of data fusion based on fuzzy theory is proposed for the temperature´s trend judgment of industry rotary kiln in this paper, which is a key for the automation of this complex industrial process. Previous temperature´s detection is based on the flame image process that is easy to be disturbed by dust and smog in the sintering strand. The algorithm proposed in this paper can overcome this disadvantage effectively. In the end, a real time expert control system based on the novel temperature detection method is shown .The practice shows that expert control system with this method can achieve high robust and good utility.
