• 1. linear approximation error: 直线逼近误差
• 2. equal-error linear approximation: 等误差线性逼近
• 3. equal-error linear approximation of profile: 等误差线性化

• 1.Based on the approximation property of fuzzy systems, a nonlinear system can be expressed as the form of linear parametric model and a modelling error term.
  根据模糊系统的逼近性质，非线性系统可以表示为线性参数化模型加上一建模误差项。

• 2.If the two preconditions are difficult to satisfy, the model error caused by the linear approximation will become difficult to control.
  如果这两个前提难以满足，由线性化近似模型带来的模型误差将变得难以控制。
