In high‐speed maglev trains, the active guidance system is responsible for centring the vehicle relative to the track, a function that becomes critical under centrifugal forces, crosswinds, and track irregularities. To address the limitations of existing control methods in multi‐disturbance environments, this paper proposes a gap‐loop active ...

PMSM Vector Control Strategy Based on Active Disturbance Rejection Controller
Based on current research into the vector control principles of the permanent magnet synchronous motor (PMSM), a control strategy founded upon an Active Disturbances Rejection Controller (ADRC) is proposed. This control strategy consists of an ADRC speed

Damping Compensation for Active Vibration Isolation System With Active Disturbance Rejection Control
The analysis of classic active disturbance rejection control (ADRC) for active vibration isolation systems (AVIS) with electromagnetic actuators demonstrates that directly applying ADRC to these systems has some shortcomings. To overcome the limitations of classic ADRC in AVIS with electromagnetic actuators, damping compensation is proposed to enhance ...

Relative Motion Error Observation of a Magnetic Screw Motor Based on Adaptive Fuzzy PI Controller
Since MSM converts rotary motion into linear motion through magnetic transmission, this means that there may be transmission errors during the transmission process. This article presents a method for observing the relative motion error between the mover and rotor of the MSM, and analyses the changes in the relative motion errors.

Longitudinal velocity control of autonomous driving based on extended state observer
Active Disturbance Rejection Control (ADRC) possesses robust disturbance rejection capabilities, making it well‐suited for longitudinal velocity control. However, the conventional Extended State Observer (ESO) in ADRC fails to fully exploit feedback from
