Analysis the Position Signal Problem in Propulsion System with Long Stator Linear Synchronous Motor

This paper investigates the position signal problem’s effect to the maglev propulsion system, presents the modeling of long stator linear synchronous motor (LSLSM), and provides an effective and robust control strategy. An efficient method based on the interpolation algorithm is proposed and validated, which achieves favourable dynamic property according to condition of the low, high velocity or even missed signal. The work of this paper provides theoretical basis and result for the optimized design of propulsion control system.
