An observer‐based controller for a class of polynomial fuzzy systems with disturbance

In this paper, a new observer-based controller for a class of polynomial fuzzy systems with disturbance is proposed. First, by some appropriate equivalence transformation of the polynomial fuzzy model, the first output-sized states can be obtained directly from the output, which eventually enables us to obtain the feedback control gain and observer-related parameters together without considering the so-called separation principle. Second, with the disturbance in mind, a PI-type observer is suggested. Finally, the sum of squares for the stability of the closed-loop observer-based control system is provided. © 2015 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
