Analysis and design of fuzzy reduced-dimensional observer and fuzzy functional observer

On the basis of the T-S fuzzy model, this paper discusses the following thr ee problems: the fuzzy reduced-dimensional observer; the general structure of the fuzzy observer; the fuzzy functional observer, for both the continuo us and discrete case, respectively. The separation property, that is, the f uzzy controller and the fuzzy observer can be independently designed, is al so addressed. The numerical simulation and the experiment on an inverted pe ndulum system are given to illustrate the soundness of these results. (C) 2 001 Published by Elsevier Science B.V.
