Design of an intelligent fuzzy control system for biomass drying process

The performance of drying equipment plays a key role in the biomass power generation. In this paper, a drying system using low-grade waste heat as the heat source based on fuzzy control is designed, which is used to control the drying process of biomass. Set the error between actual straw moisture content and set-point, and rate of change of error as two inputs, the biomass flow rate can be acquired by the fuzzy logic computing as the output. The running result shows that the design of the fuzzy control system is a reliable and precise control method for drying corn straw. The control framework for biomass drying process can also be applied to a variety of biomass, such as, cotton stalk, rice straw, wheat straw, et al.
