Feedback control of nonlinear differential algebraic systems using hamiltonian function method

Science in China(Series F) 2006年第4期49卷 436-445页

作者： LIU Yanhong LI Chunwen WU Rebing Department of Automation Tsinghua University Beijing 100084 China Frick Laboratory Princeton University Princeton NJ 08544 USA

The stabilization and H∞ control of nonlinear differential algebraic systems （NDAS） are investigated using the hamiltonian function method. Firstly, we put forward a novel dissipative hamiltonian realization （DHR） structure and give the condition to complete the hamiltonian realization. Then, based on the DHR, we present a criterion for the stability analysis of NDAS and construct a stabilization controller for NDAS in absence of disturbances. Finally, for NDAS in presence of disturbances, the L2 gain is analyzed via generalized Hamilton-Jacobi inequality and an H∞ control strategy is constructed. The proposed stabilization and robust controller can effectively take advantage of the structural characteristics of NDAS and is simple in form.

Simultaneous stabilization of a class of nonlinear descriptor systems via hamiltonian function method

This paper studies simultaneous stabilization of a class of nonlinear descriptor systems via the hamiltonian function method. Firstly, based on the hamiltonian realization of the nonlinear descriptor systems and a suitable output feedback, two nonlinear descriptor systems are equivalently transformed into two nonlinear hamiltonian differential-algebraic systems by a nonsingular transformation, and a sufficient condition for two closed-loop systems to be impulse-free is given. The two systems are then combined to generate an augmented dissipative hamiltonian differential-algebraic system by using the system-augmentation technique, based on which a simultaneous stabilization controller and a robust simultaneous stabilization controller are designed for the two systems. Secondly, the case of more than two nonlinear descriptor systems is investigated, and two new results are proposed for the simultaneous stabilization and robust simultaneous stabilization, respectively. Finally, an illustrative example is studied by using the results proposed in this paper, and simulations show that the simultaneous stabilization controllers obtained in this paper work very well.

Adaptive H-infinity control of synchronous generators with steam valve via hamiltonian function method

控制理论与应用（英文版） 2006年第2期4卷 105-110页

作者： Shujuan LI Yuzhen WANG School of Control Science and Engineering Shandong Unversity Jinan Shangdong 250061 China

Based on hamiltonian formulation, this paper proposes a design approach to nonlinear feedback excitation control of synchronous generators with steam valve control, disturbances and unknown parameters. It is shown that the dynamics of the synchronous generators can be expressed as a dissipative hamiltonian system, based on which an adaptive H-infinity controller is then designed for the systems by using the structure properties of dissipative hamiltonian systems. Simulations show that the controller obtained in this paper is very effective.

In this article, a nonlinear robust（NR） control is designed for static synchronous series compensator（SSSC） to improve transient stability and oscillation damping of power system. By taking the parameter deviations, external disturbances and unmodeled dynamics into account, the nonlinear dynamic model of SSSC can be changed into a hamiltonian structure with the help of coordinate transformation. Based on the hamiltonian structure of SSSC, a nonlinear robust control is designed for SSSC. Numerical simulation results on the two-area four-machine power system demonstrate the robustness and effectiveness of the proposed nonlinear robust control in comparison with the direct feedback linearization（FL） control. The study results show that the nonlinear robust control has better performance than the FL control.
