Abstract
We investigate the high gain asymptotic behavior of multivariate root loci. The proposed method groups the unbounded root loci of a non-singular m-input/m-output system into several Butterworth patterns as the gain tends toward infinity. A geometric technique is proposed that provides direct realization of these asymptotic Butterworth patterns. Since the method can determine integer as well as non-integer orders of these patterns,the method can be used to identify maldesigned conditions. Finally, the proposed method is extended to optimal root loci and three examples are presented that illustrate the effectiveness of the approach.
