摘要:
A method for the global analysis of non-linear systems is presented which provides a framework for the analysis of both continuous and discrete-time non-linear systems for the diverse range of model types. By extending a numerical approach to enable the analysis of non-linear parametrized non-linear systems a global perspective is achieved that is difficult to obtain using analytical methods alone. Simple examples are used to illustrate how the method characterizes the system stability at the same time as detecting typical qualitative bifurcation phenomena. A non-linear feedback system is analysed in order to show how the approach provides both qualitative and quantitative information over a defined region of the system parameter space. The method proves to be a powerful tool which can be used to probe the non-linear characteristics of a system.

摘要:
The present work shows the application ofH∞optimal control to the imperfect model-following problems where exact model-following fails to be implemented. The significance of this work lies in the improvement of the ill-conditioning problem in theH∞algorithm for the strictly proper plant. This is achieved by perturbing the plant in a suitable way. The optimal results can be recovered asymptotically under certain conditions for the scalar case. Such an approach provides a way to solve the problem when the existingH∞algorithm fails. This paper also highlights the degree constraints of choosing an ideal model. The model-following controller is illustrated by practical examples and compared withH2results.

摘要:
A projective product spaces model is used to analyse decentralized systems. The degree of the pole placement map is computed. The conditions under which the degree is odd are also given. Twin lift systems are studied. It is proved that the poles of a twin lift system can be assigned to any values by local static and local dynamic feedback laws if and only if the system is jointly controllable.
