| Abstract: |
| In this paper, the numerical approximation characteristics of fuzzy system are discussed, and the influence of approximation error and initial state error on fuzzy system are analyzed. Finally, an important conclusion is obtained that under some conditions, fuzzy system output differs little from that of the actual system. |
| Key words: Universal approximation, fuzzy system, system identification, approximation error. |
