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 ...

L2 gain disturbance attenuation of PMSM based on Hamiltonian systems control theory

2010 8th World Congress on Intelligent Control and Automation, 2010
A novel L2 gain disturbance attenuation control algorithm is presented for permanent magnet synchronous motor (PMSM) based on port-controlled Hamiltonian (PCH) systems theory. First of all, a PCH system model of PMSM is established. Then, using the interconnection and damping assignment method, the PCH controller of the PMSM system is designed when the

Nonlinear Decentralized Disturbance Attenuation Excitation Control for Power Systems With Nonlinear Loads Based on the Hamiltonian Theory

IEEE Transactions on Energy Conversion, 2007
A novel nonlinear control scheme for disturbance attenuation of structure preserving multimachine power systems based on Hamiltonian theory is proposed in this paper. The proposed control scheme includes two steps: first, the dissipative Hamiltonian realization of structure preserving power system is completed using the singular perturbation approach ...

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.

Optimal control of open quantum systems: A combined surrogate Hamiltonian optimal control theory approach applied to photochemistry on surfaces

The Journal of Chemical Physics, 2012
In this paper, control of open quantum systems with emphasis on the control of surface photochemical reactions is presented. A quantum system in a condensed phase undergoes strong dissipative processes. From a theoretical viewpoint, it is important to model such processes in a rigorous way.

Coordinated control of excitation and SVC in multi-machine power system based on pseudo-Hamiltonian theory

2012 IEEE Power and Energy Society General Meeting, 2012
Coordination control has a substantial potential to enhance the power system stability and has drawn considerable attention for years in the literature. In this paper, the coordination of the excitation and SVCs is studied. The pseudo-generalized Hamiltonian system is introduced, which has a more general form and a wider range of application.

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 ...
