In this paper, the numerical approximation characteristics of fuzzy system are discussed, and the influence of approximation error and initial state error on fuzzy system are analyzed.

该文讨论了模糊系统的数字逼近特性，同时分析了逼近误差和初始状态误差对模糊系统的影响。

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。

So a compensator is constructed, which is compensates the approximation error's effect on system output at the condition of the approximation error thought as disturbance of the system.

所以利用系统跟踪误差构造线性最优补偿器，该补偿器用于减少逼近误差对系统跟踪误差的影响。
