Abstract : A new graphical procedure for the analysis of nonlinear multivariable systems is presented. The method uses the eigenvalue loci of the linear part of the system and the describing function loci of the nonlinear parts, and is an extension of the eigenvalue methods first introduced by Bohn for the analysis of linear multivariable systems. For some special classes of systems, it is shown that very realistic stability estimates can be obtained in a simple manner. Examples are given to illustrate the use of the method and the stability bounds obtained are compared with those resulting from the use of other stability criteria. (Author)
