| 摘 要： | 详细讨论了较常见的21种模糊蕴涵算子构成的模糊控制器及其响应函数.主要结果是,异常蕴涵算子模糊控制算法都可归结为某种插值方法,它们相应的模糊控制器均具有函数逼近的泛性且彼此等效;而正常蕴涵算子(包括正规蕴涵算子的导出算子)模糊控制算法均非插值方法,其模糊控制器都不具有函数逼近的泛性,除Zadeh蕴涵算子外,这些正常蕴涵算子的模糊控制器均只具备阶跃输出功能且在一定意义下相互等效.

| Abstract: | Fuzzy controllers and their response functions are studied which are based on 21 commonly used fuzzy implication operators.Fuzzy controllers based on irregular implication operators in the 21 ones are regarded as some interpolation functions so that these controllers are universal approximators and are equivalent to each other.Except for Zadeh operator,fuzzy controllers based on regular implication operators in the 21 ones are not universal approximators,they are controllers with only step output ability. |
