基于模糊控制的解析結構理論，設計了輸入變量采用三角形、全交迭，等差間距分布的隸屬函數，輸出變量采用對稱、均勻分布的單點隸屬函數和線性控制規則的二維模糊控制器，推導了模糊控制器的解析表達式。利用Lyapunov 第二法論證了該模糊控制系統在平衡點處的局部穩定性，并證明了模糊控制器的一致逼近性。

Abstract: Based on the theory of analytical structure, a fuzzy controller with two inputs and one output is designed in this paper, whose input-membership is triangular, full-overlapped, unevenly and difference-space distribution, output-membership is symmetric, singleton and evenly distribution. With the analytical expression of fuzzy controller, it is discussed that the fuzzy control system has the same local stability as a linear PI controller at equilibrium point, and then it is proved that the fuzzy controller is universal approximation.
