A Deadbeat Direct Thrust Control for Permanent Magnet Linear Synchronous Machine Considering Parameter Asymmetry

Permanent Magnet Linear Synchronous Machine (PMLSM) has the inherent drawbacks of parameter asymmetry due to the end effect, and is hard to be eliminated by machine topology optimization. Asymmetrical parameter in PMLSM would cause high thrust ripple, especially under accelerate condition. In order to reduce the thrust ripple and have high transient response, this paper proposes a Deadbeat Direct Thrust Control (DB-DTC) considering parameter asymmetry and verified by simulation experiment.
