Abstract

This paper investigates optimal design and control simulation of a high-accelerate double-sided permanent-magnet linear synchronous motor (DS-PMLSM) with water cooling system. Firstly, the topology structure is presented, which adopting pure permanent magnets (PMs) as mover for high acceleration, and then the optimal design is carried out. Secondly, the electromagnetic performance is analyzed based on the finite element method (FEM), and the armature inductance under different armature current is calculated. Thirdly, with the obtained inductance curve, a servo control system under different working conditions based on space vector pulse width modulation (SVPWM) is established by MATLAB/Simulink. Finally, the control performance is simulated by static and dynamic response simulation, which is consistent with the design purposes.
