Rotor angular position feedback control: BayerRecent Research Landscape

Mechanical rotor seizure and sensor failure lead to total drive system immobilization. These innovations utilize specific current injection and emergency commutation sequences to restore rotation without physical intervention.

What technical problems is Bayer addressing in Rotor angular position feedback control?

Rotor position estimation inaccuracy

(14)evidences

Inaccurate angular feedback leads to torque instability and reduced efficiency in field-oriented control. Precise error mitigation ensures safe operation and prevents inverter switching failures.

Phase current sensor inaccuracy

(8)evidences

Measurement offsets and sensor errors in phase current detection lead to inaccurate rotor position estimation and torque ripple. Eliminating these errors ensures precise motor control and prevents system instability.

Unreliable rotor position feedback

(4)evidences

Mechanical blockages and sensor failures prevent accurate determination of rotor orientation. Resolving these feedback interruptions ensures continuous torque delivery and prevents system immobilization during faults.

Harmonic signal distortion

(4)evidences

Imprecise synchronization between the electrical phase and mechanical rotor position leads to torque ripple and efficiency loss. Accurate feedback ensures optimal power conversion and stability in dynamic drive systems.
