In this paper, we use center manifold theory to give a new result aboutthe stabilization of nonlinear systems. First an illustrative example is given to show ourmotivation. Then the main result by means of center manifold and homogeneous stabilityis proposed, and its application to a generalized form without the usual relative degreebecause of singularity is given.

Feedback Equivalent Forms of Forced Hamiltonian Systems

Fast and Robust Control of Excitation systems: A Finite-time Method

第十九届中国控制会议

作者： yiguang hong Zairong Xi Daizhan Cheng huashu qin institute of systems science, The chinese academy of sciences, beijing 100080, china

This paper addresses the problem of feedback equivalence of forced Hamiltonian systems. This class of systems, with many (potential) applications in the areas such as mechanical systems and power systems, have been studied widely in recent years. Feedback equivalence is one of the most interesting problems about the thoery of generalized Hamiltonian systems. Here, instead of modifying its structure matrix, we change the Hamiltonian function of the considered system via feedback, which may be helpful in further practical design.

关键词： forced Hamiltonian systems feedback equivalence, Hamiltonian function.

Journal of systems science and systems Engineering 2001年第2期13卷 148-161页

Using finite-time control approach, this paper proposes a new design method for nonlinear robust excitation control of a widely used 5th-order model of synchronous generators. The finite-time excitation controller achieved here can improve the system′s behaviors in some aspects such as quick convergence and robustness for uncertainties. Simulations demonstrate that the finite-time excitation controller is more effective than some other excitation controllers.
