An approach to the obtaining of knowledge bases for MIMO fuzzy control: application to a nonlinear thermal system control

This paper presents an approach to obtaining knowledge bases for MIMO fuzzy control and a method for taking into account the input-output couplings, which allows us to simplify the rule bases and to tune the difference of sensibility of the outputs toward the inputs. To illustrate this approach we deal with a real process. The controlled system we consider is a nonlinear thermal system, which has three inputs and two outputs strongly coupled.
