【摘要】 分析了ＭＡＴＬＡＢ在鲁棒设计中应用的一些问题，指出了ＭＡＴＬＡＢ５．０～５．３版本的μ综合程序Ｄ—Ｆ迭代有过早停止的问题，给出了修正的办法，使Ｄ—Ｆ迭代可以正常进行并得到正确的计算结果。对基于ＬＭＩ法的鲁棒设计，本文对具体应用时会遇到的矩阵变量定义、ＬＭＩ项描述以及求矩阵的零空间等问题，介绍了处理方法。最后结合一个典型的鲁棒设计中一组ＬＭＩ问题的求解，详细讲解了编程中的问题和处理方法。更多还原

【Abstract】 Some problems of MATLAB in robust design are discussed. It is pointed out thatthe D-F iteration μ synthesis program in MATLAB 5.0 ~ 5.3 stops too early. A revisingmethod is given to get the D-F iteration run normally and correctly. For LMI- based robustdesign, correct methods of defining matrix variables, LMI terms and matrix null spacecalculating are given. The problem in programming and the methods to solve a set of LMIsare explained in detail with a typical robust design problem.更多还原
