Intelligent control system of an industrial lime kiln process.

Abstract In the face of strong competition, the pulp and paper industry is aiming at higher pro"tability through increased productivity and the reduction of costs. In addition, on the global scale the industry is facing increasing market demands for higher product quality, more specialty products and improved production #exibility and environmental protection. Consequently, extensive research is being conducted to improve existing processes. One alternative, which is gaining increasing attention within the industry, is the improved control of existing processes by means of intelligent systems. In this paper, an intelligent kiln control system is presented. In the system, neural network models are used in conjunction with advanced high-level controllers based on fuzzy logic principles and a novel linguistic equation approach. Finally, the testing results of the system are presented and discussed

ACTIVITY REPORT 2007 - 2010

Aalto University School of Science and Technology is the largest and oldest institute of engineering education in Finland. The University campus is situated about 10 km west of Helsinki in the Otaniemi area, in the township of Espoo. The number of undergraduates is about 12 000 and that of postgraduates about 2800. The degrees offered in the School of Science and Technology are the basic Master’s degree in engineering, architecture or landscape-architecture (minimum 4.5 years) and the postgraduate degree Doctor of Technology (minimum 4 years). The Department of Biotechnology and Chemical Technology comprises eight research groups (= eight full professorships): Biochemistry, Microbiology, Bioprocess Technology, Chemical Engineering, Plant Design, Industrial Chemistry, Polymer Technology and Process Control. The Laboratory of Process Control and Automation, as a member of the department was founded in 1987. The aim of the laboratory is to serve all fields of process technology - chemical, metallurgical and forest products - in terms of process automation. The laboratory gives courses in process modelling, simulation, control, optimization and automation as well as in production control. The undergraduate students typically have a few years background of process engineering studies, after which a one-to-two-year portion of automation studies. Post-graduate students typically work in the field of process technology - either in the industry or in research institutes or universities - while studying. This report describes briefly the staff, teaching, facilities, research and other activities of the Laboratory of Process Control and Automation during 2007 - 2010
