Abstract:A new kind of fuzzy modeling method to construct an approximate solution to a differential equation is proposed in this paper. The proposed method is based on the interpolation mechanism of rectangular pyramid fuzzy system and ends up with a solution to a nonlinear differential equation with variable coefficients. The proposed fuzzy modeling method is applied to model time-invariant second-order freedom movement systems, so a new input Coutput model and a new state-space model are constructed, respectively. Simulation results show that the proposed modeling method is effective in approximating the original system. ? 2017, Taiwan Fuzzy Systems Association and Springer-Verlag Berlin Heidelberg.
