【Abstract】 In order to improve the stability precision of the fuzzy controller,fuzzy reasoning operator is studied and it is found fuzzy control table which is inferred by using probability operator is of high control precision. Under the environment of Mathematiocs,the program of the fuzzy reasoning is achieved. It offers the convenient conditions for the research of fuzzy control,provides the control table of typical fuzzy controller, and increases the quantity field. The influence of the distribution of membership function on the control table is studied, and it is found the data in the control table that produced by uneven membership function is fluctuant.The result of simulation shows that the stability control precision is obviously improved by increasing fuzzy quantity fields.更多还原
