Nonlinear Robust Control of Dual-Excited Hydroturbine Generator based on Hamiltonian Energy Theory

2007 IEEE International Conference on Control and Automation, 2007
Based on Hamiltonian energy theory, this paper proposes a water-gate and excitation controller for dual-excited synchronous generator driven by hydroturbine, such that both the rotor angle and voltage can achieve their stability. The system consists of a hydraulic turbine and a synchronous generator and is described by a sixth-order model.

Hamiltonian surface shaping with information theory and exergy/entropy control for collective plume tracing

International Journal of Systems, Control and Communications, 2010
The goal of this paper is to design and analyse distributed decentralised control laws for a team of robots performing collective plume tracing based on Hamiltonian surface shaping, information theory, and exergy/entropy control. The process begins with the design of a kinematic controller based on the application of static and dynamic stability ...

Application of Floquet theory to formation flying in elliptic orbits via a Hamiltonian structure-preserving control

Aerospace Science and Technology, 2019
Abstract In this study, an improved Hamiltonian structure-preserving controller is applied for formation flying in elliptic orbits. The Lyapunov-Floquet theory is applied to the Tschauner-Hempel (TH) equation in order to generate its transformed form with two zero eigenvalues and two pairs of imaginary eigenvalues.

Robust control of variable-speed adjustable-pitch wind energy conversion system based on hamiltonian energy theory

2009 International Conference on Sustainable Power Generation and Supply, 2009
Based on Hamiltonian energy theory, this paper proposes a pitch angle and excitation torque controller for the wind energy conversion systems (WECS), such that the closed-loop system can achieve its stability. Furthermore, in the presence of disturbances, the closed-loop system is finite-gain L2 stable by the Hamiltonian controller.

Coordinated control of static synchronous compensator and automatic voltage regulator in multi-machine power systems using pseudo-generalized Hamiltonian theory

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2013
Flexible alternating current transmission system devices are widely used to enhance the power transfer limit and stability improvement in transmission networks. They also help damp out both local and inter-area low-frequency oscillations. Using pseudo-generalized Hamiltonian theory, this article investigates the coordinated control of automatic ...

Pseudo-generalized Hamiltonian theory and its application in nonlinear stabilizing control of multi-machine system with losses

2011 International Conference on Electric Information and Control Engineering, 2011
This paper presents the pseudo-generalized Hamiltonian theory which has a more general form and a wider range of application. A new Lyapunov candidate function is proposed and proven to qualify as a true Lyapunov function under some assumptions. Then, we take multi-machine power system considering transfer conductance as an example to illustrate the ...
