Abstract
In this paper, a fuzzy adaptive internal model controller (FAIMC)
for open-loop stable plants is presented. The control scheme consists of
two parts: a fuzzy dynamic model and a model-based fuzzy controller. A
fuzzy dynamic model, which serves as the internal model of the FAIMC is
identified online by using the input and output measurement of the
plant. Based on the identified fuzzy model, the fuzzy controller is
designed to minimize an H2 performance objective. This FAIMC
scheme has been successfully applied to control the flow rate in a
laboratory-scale process control unit from Bytronic. The experimental
results demonstrate that this class of control scheme is appropriate for
control of time-varying stable plants with time delay. The control
system is also shown to possess satisfactory robust performance
