\n this paper, a novel control strategy applied in permanent magnet linear synchronous motor (PMLSM) drive system is proposed based on Euler-Lagrange (EL) equation and passivity-based control (PBC) theory. The state equation of PMLSM in d-q reference frame is established. Some matrices with special structures are deduced to transform the state equation into EL form. From the energy point of view,...
This paper analyzes the circulating current of parallel three-level NPC inverters in the transportation traction system with long stator linear synchronous motor, presents the modeling, and provides an effective and robust control strategy. Parallel operation of inverters is an efficient way to enhance the capacity and reliability of inverter systems and convenient for modularization. The provided...
