Interval type-2 fuzzy T-S modeling for a heat exchange process on CE117 Process Trainer

In this paper, a modified interval type-2 fuzzy T-S modeling method is applied to a heat exchange process on the equipment CE117 Process Trainer. First, subtractive clustering method combined with least square method is employed to build the type-1 fuzzy T-S model. Then the type-2 fuzzy T-S model is obtained from the type-1 model through unconstrained optimization where the Nelder-Mead Simplex method is utilized. Finally, the results of the experiment prove the efficiency of the proposed algorithm.
