本文研究了T-S模糊模型在未知输入和干扰同时影响系统状态和输出时的观测器设计问题。以线性矩阵不等式（LMI）形式给出了设计未知输入T-S观测器的充分条件。连续时间和离散时间的情况下进行了研究。通过使用中间变量引入松弛。扩展到不可测的决策变量的情况下也给出了。最后给出了一个数值例子来说明所给结果的有效性。
This paper deals with the observer design for Takagi-Sugeno (T-S) fuzzy models subject to unknown inputs and disturbance affecting both states and outputs of the system. Sufficient conditions to design an unknown input T-S observer are given in linear matrix inequality (LMI) terms. Both continuous-time and discrete-time cases are studied. Relaxations are introduced by using intermediate variables. Extension to the case of unmeasured decision variables is also given. A numerical example is given to illustrate the effectiveness of the given results.
