Novel Active Disturbance Rejection Control for Permanent Magnet Linear Synchronous Motor without Sensor
A novel ADRC scheme is proposed for permanent magnet linear synchronous motor without sensor, which has nonlinear, multi-load disturbance and parameter time-varying characteristics. Extended states observer (ESO) in ADRC can real-time estimate speed, location and uncertain disturbance, and the parameters artificial is used to optimize by fish swarm algorithm. Finally, simulation results confirm the proposed strategy has better tracking performance and robustness than the traditional one.
