说明：  模糊控制的一级倒立摆仿真，采用TS模型，TTS模糊模型，是非线形复杂系统模糊建模中一个典型的模糊动态模型。这类模型采用的模糊规则：其前件是依据系统输入、输出间是否存在局部线形关系来进行划分；而其后件是多项式线形方程来表达，从而构成各条规则间的线形组合，使非线形系统的全局输出具有良好的线性描述特性。(Fuzzy Control of an inverted pendulum simulation, using the TS model, TTS fuzzy model, a non-linear modeling of complex systems in a typical fuzzy fuzzy dynamic model. Such models using fuzzy rule: whether it is based on local linear relationship exists between the system input and output to the front piece is divided subsequent pieces are linear polynomial equations to express, thus constituting a linear combination between each rule that non- Global output linear system has good linearity characterization.)
