For the models by MMFI is a nonlinear differential equation with variable coefficients and the 'nonlinearity' brings discommodiousness to analyse the nature and quantification of a control system, it applies brim linearization method to better MMFI. By transforming 'triangle wave' membership functions of the base elements into 'rectangle wave' membership functions, we get three models which represent different aspect respectively. By simulating second order system and analysing the errors of the results, a conclusion is drawn, that is, the model obtained by brim linearization method has a good precision in contrast with the real model.

由于模糊推理建模法得到的模型是变系数非线性微分方程，这种&非线性&对该控制系统的某些定性或定量分析带来不便，因此应用边缘线性化方法对模糊推理建模法进行改进，将基元的隶属函数由&三角波&改成&矩形波&，从而得到了三个模型，这三个模型各有侧重，通过对二阶系统进行仿真，分析仿真结果，从而给出了关于边缘线性化方法的结论，即由边缘线性化方法得到的系统模型对该系统的真实模型有较高的逼近精度。
