Abstract

This paper presents a Hamiltonian-based control strategy for permanent magnet synchronous motor (PMSM) drives supplied through an LC-filtered DC link. The proposed control strategy combines a port-controlled Hamiltonian (PCH) framework with a Lyapunov-based observer to regulate system energy and enhance robustness. A speed tracking controller generates the q-axis current reference for the inner Hamiltonian current controller, and the stability of the overall closed-loop system is verified using Lyapunov analysis. Experimental results are obtained from a real-time PMSM drive platform under step load disturbances. The results show that the proposed controller improves dynamic response and electrical performance compared to a conventional PI controller. In particular, the DC-link voltage ripple is reduced from approximately 21% to 6%, while the stator current total harmonic distortion (THD) decreases from 11.95% to 6.77%.
