说明：  运用模糊数学的基本理论和方法把规则的条件，操作用模糊集表示，把这些模糊规则以及有关信息作为知识存入计算机知识库中。然后计算机针对情况运用模糊推理可实现对PID参数的最佳调整
(The basic theory and method of fuzzy mathematics are used to express the conditions of the rules and the fuzzy sets of the operation, and these fuzzy rules and the relevant information are stored in the computer knowledge base as knowledge. Then the computer can optimize the PID parameters according to the fuzzy reasoning.)
