采用知形域上分片双一次插值方法对模糊控制表进行插值，使在线控制时的模糊控制器输入、输出值均取连续可变量，克服了普通模糊控制系统因控制器输入、输出变量量化所造成的控制精度低与可能出现的稳态颤振等缺点。仿真结果表明该方法具有优良的控制品质。
The biscuit interpolation method is used to interpolate the fuzzy control table in the domain of knowledge so that the input and output values of the fuzzy controller in the on-line control are all continuously and variably variable, which overcomes the error of the ordinary fuzzy control system due to the controller input and output variable quantification Resulting in low control accuracy and possible steady-state chatter and other shortcomings. Simulation results show that the method has excellent control quality.
