A Concept for the Fuzzy-adaptive Temperature Control of MIMO Systems
نویسندگان
چکیده
Many technical systems for the control of temperatures require a MIMO (multiple input multiple output) model for the control design. This problem arises in systems with higher geometric dimensions, more than one actuating value, strongly coupled structure, or extreme precision requirements. In this case, the assumption of equal temperatures in the complete device is not valid. If higher temperatures occur, a nonlinearity have to be concerned mainly caused by the thermal radiation depending on the absolute temperature values but also by actuating characteristics of the heaters. Examples for this type of systems are some chemical reactors, heat exchangers, glass melting processes and furnaces for crystal growth processes.
