| Abstract: | A statistical quantitative sensitivity measurement for fuzzy system, which has significant theoretical and practical importance, was investigated. By using the proposed sensitivity measurement, the quantitative relationship between the input perturbation and the output perturbation of fuzzy system could be computed analytically and efficiently. In addition, the sensitivity of each layer in fuzzy system could also be measured simultaneously while computing the sensitivity of fuzzy system. The proposed sensitivity measurement can do great contribution to the rapid performance evaluation of fuzzy system. Numerical simulations illustrate the correctness and effectiveness of the proposed sensitivity measurement. |
| Keywords: | fuzzy system quantitative sensitivity measurement input perturbation output perturbation |
