Abstract In this paper we develop a new systematic procedure for controlling non linear plant based on fuzzy modelling and control. The fuzzy controller design is based on local linear models smoothly connected by fuzzy membership functions all of which can be determined directly from logged data. The practical value of the method is tested on the simulation of …

To summarize the coal mill controls, they may be divided basically into two major categories: 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
