Abstract

The application of frequency domain methods to the study of a class of multivariable nonlinear feedback systems is considered within the context of a comprehensive interactive graphics design procedure and a new computational method is outlined for the determination of limit cycle operation which emphasises the effects of off diagonal system elements. It is shown how compensation can be applied using classical graphical design methods to avoid critical regions in the frequency domain. Two examples of use are given.
