Fuzzy systems and their response functions based on commonly used fuzzy implication operators
常见模糊蕴涵算子的模糊系统及其响应函数

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.
