摘　　要：病态对象因为其高条件数的特点为系统的鲁棒性能设计带来困难，μ综合中M阵具有四块结构，适于求解这类病态问题，而且结构奇异值μ是鲁棒性能的充要判据．本文给出D－K迭代中初值D0阵的选取方法，可以较快地求得μ综合解，文中还以精馏塔鲁棒控制设计为例进行了说明．It is difficult for the robust per formance design of ill-conditioned plant because of its high condition number. With the four-block matrix M,μ-synthesis could deal with the design of ill-conditioned plant and μ is necessary and sufficient condition for robust per formance. In this paper a way to get an appropriate initial matrix D0 in D-K iterations is presented,with the robust performance design of high-purity distillation as an example.
