Abstract :
In this paper, a formula for computing the real decentralized fixed mode radius and real unstable decentralized fixed mode radius for a linear time-invariant system is presented. These results give a measure of how "near" a decentralized LTI system is from having an unstable decentralized fixed mode (DFM) present, and are important in application problems where decentralized control is typically used, e.g. in chemical process control, transportation problems, electric power systems, etc. A number of representative industrial system examples are given in the paper to illustrate the type of results that can be obtained.
