Harmonic Disturbance Rejection Control for Magnetic Field Compensation Applications

A simple control strategy was studied for harmonic disturbance rejection in magnetic field compensation systems for low-field magnetic resonance techniques. The strategy is based on the simultaneous action of a conventional PID and a selective harmonic-compensation controllers. The system consists o...
