We propose a two-stage solution where in the first step the semi-infinite constraints are converted to linear matrix inequalities using the generalized sign-definiteness lemma, and in the second step, we use an iterative algorithm based on alternating convex search (ACS). Via simulations we ...

The reference[1]introduced sign-reserving transformation,and directly judged the positive definiteness of the matrix by the sign of main diagonal elements of the sign reserving equivalent triangular matrix. [1]文中介绍利用矩阵的初等保号变换,根据其保号等价矩阵的主对角线元素的符号直接判别矩阵的正定性...
