| Περίληψη: | The root-locus method dictates a set of practical rules which enable the graphical estimation of the closed-loop poles as a function of the feedback gain. One of the difficulties in extending the method has been the lack of appropriate definitions of multivariable system zeros and, hence, the lack of insight into their properties. In recent years, however, a number of equivalent definitions for multivariable zeros have been introduced, so that some of the fundamental properties of the zeros of scalar systems can be generalized. As a first step toward the development of a multivariable root-locus theory, it is the purpose of the paper to explore the asymptotic behavior of the root-loci and provide rules for its graphical construction. |
