A PHASE-ADVANCED FILTER FOR ROBUST RESONANCE CANCELLATION |
摘要 |
A filter for attenuating a resonance mode without substantial phase margin loss. The filter comprises a transfer function having an additional pole, such that the phase of the input signal is advanced. The phase-advanced filter substantially attenuates all frequencies above a selected center frequency while avoiding substantial phase margin loss. |
