It is difficult to design the closed loop gain shaping controller when the controlled plant is not a square matrix, because it is involved in the pseudo inverse of matrix.

在被控对象为非方阵的系统中，由于求解控制器时涉及到矩阵求伪逆问题，很大程度上增加了闭环增益成形算法的难度。

Then, an algorithm based on iterative linear matrix inequality (ILMI) was proposed to compute the static output feedback gain of continuous uncertain T-S closed-loop fuzzy system.

为了计算连续不确定T - S闭环模糊系统的静态输出反馈增益，提出了基于迭代线性矩阵不等式的算法。
