TLDR
In this paper, a detailed analysis of the stages involved in the design of a controller for a gas turbine is presented, which leads to a new type of controller which may be regarded as a multivariable version of a classical lead compensator.Abstract:
Following a brief outline of the inverse Nyquist design method as applied to multivariable systems, its application is illustrated by a detailed analysis of the stages involved in the design of a controller for a gas turbine. This leads to a new type of controller which may be regarded as a multivariable version of a classical lead compensator. Comparison with more familiar multivariable design methods shows the inverse Nyquist method to be superior, not only in the controllers it leads to, but also in the information it gives the designer.read more

Design of multivariable control systems using the inverse Nyquist array
TL;DR: The inverse Nyquist array as discussed by the authors is a set of diagrams corresponding to the elements of the inverse of the open-loop transfer function of a control system, which can be used to investigate the stability of multivariable control systems.
