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

Stability Improvement of Cascaded Power Conversion Systems Based on Hamiltonian Energy Control Theory

IEEE Transactions on Industry Applications, 2020
It is well known that the interaction between cascaded individually designed power conversion systems can cause instability. To overcome this issue, a Hamiltonian energy control scheme is proposed, which is based on passivity control theory and port-controlled Hamiltonian framework.

Adaptive tracking control of unmanned underwater vehicles with compensation for external perturbations and uncertainties using Port-Hamiltonian theory

Ocean Engineering, 2020
Abstract This paper addresses the tracking control problem of unmanned underwater vehicles under the condition of external disturbances and unmodeled dynamics using Port-Hamiltonian theory. By introducing Port-Hamiltonian theory, conventional UUVs dynamics can be transformed into Port-Hamiltonian form with insightful expressions.

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.
