摘要
The paper is concerned with the computation of the maximum ranges of stabilizing proportional-integral (PI) controllers for multiple-input and multiple-output (MIMO) systems. A time-domain scheme is proposed by converting the considered problem to a robust stability problem for a polytopic system. An algorithm based on linear matrix inequality (LMI) is established to find the maximum ranges.
