Sensorless control for high-speed linear synchronous motor based on a deadbeat predictive observer

Sensorless control technology shows promising application prospects in electromagnetic sled systems due to its advantages of high reliability and cost-effectiveness. However, electromagnetic sled systems present special operating conditions including high power, short-duration operation, reciprocating motion, time-varying parameters, and strong nonlinear disturbances, imposing higher demands on the dynamic response and robustness of observers. To address this issue, this paper proposes a deadbea
