Nonlinear Control for STATCOM Based on Generalized Hamiltonian System Theory

2014 Sixth International Conference on Intelligent Human-Machine Systems and Cybernetics, 2014
Considering nonlinear and energy dissipation characteristics of STATCOM, realization of the generalized Hamiltonian system based on the model of system, and design nonlinear controller. This paper discussed the generalized Hamiltonian system and its realization, and established nonlinear dynamic model according to the work principle of STATCOM ...

Robust control of permanent magnet synchronous motor based on Hamiltonian system theory

2013 25th Chinese Control and Decision Conference (CCDC), 2013
Permanent magnet synchronous motors (PMSM) always suffer to disturbances of un-modeled dynamic and external world. This paper investigates the double-loop robust control of PMSM based on Hamiltonian system theory. First, the dynamic model of the PMSM is transferred to its equivalent Hamiltonian system model which can extensively present the physical ...

Beyond average Hamiltonian theory for quantum sensing

Physical Review Research
The application of average Hamiltonian theory (AHT) to magnetic resonance and quantum sensing informs pulse sequence design, for example, by providing efficient approximations of spin dynamics while retaining important physical characteristics of system ...

Passivation controller design for turbo-generators based on generalised Hamiltonian system theory

IEE Proceedings - Generation, Transmission and Distribution, 2002
A method of pre-feedback to formulate the generalised forced Hamiltonian system model for speed governor control systems is proposed. Furthermore, passivation controllers are designed based on the scheme of Hamiltonian structure for single machne infinite bus and multimachine power systems.

Turnpike in Nonlinear Optimal Control Problems With Indefinite Hamiltonian

IEEE Control Systems Letters
We provide a sufficient condition to ensure turnpike for general nonlinear control systems. The main result of this letter exploits the connection between turnpike and the hyperbolicity of the corresponding optimality system and combines it with the ...

Sturmian theory for linear Hamiltonian systems without controllability

Mathematische Nachrichten, 2011
Summary: We present Sturmian separation and comparison theorems for linear Hamiltonian systems when no controllability assumption is imposed. This generalizes the traditional results of W. T. Reid for controllable (or normal) linear Hamiltonian systems to the possibly abnormal case.

Orbit Transfer using Optimal Control Theory

2019 3rd International Conference on Recent Developments in Control, Automation & Power Engineering (RDCAPE), 2019
Main objective for the orbit transfer problem is optimal minimization of time and fuel. In this research, 2-body system is represented by a nonlinear dynamic system.

On Casimir functionals for field theories in Port-Hamiltonian description for control purposes

IEEE Conference on Decision and Control and European Control Conference, 2011
We consider infinite dimensional Port-Hamiltonian systems in an evolutionary formulation. Based on this system representation conditions for Casimir densities (functionals) will be derived where in this context the variational derivative plays an extraordinary role. Furthermore the coupling of finite and infinite dimensional systems will be analyzed in

Infinite-dimensional port-Hamiltonian systems: a system node approach

MCSS. Mathematics of Control, Signals and Systems, 2023
We consider an operator-theoretic approach to linear infinite-dimensional port-Hamiltonian systems. In particular, we use the theory of system nodes as reported by Staffans (Well-posed linear systems.
