SYSTEM AND METHOD FOR WHEEL DISTURBANCE ORDER DETECTION AND CORRECTION
摘要
An active nibble control (ANC) includes an anti-notch filter that increases the gain margin of the control and, therefore, greater disturbance rejection. The closed loop frequency response of the ANC is further enhanced by the addition of a lag-lead phase compensator filter. The addition of the lag-lead compensation filter allows use of the higher ANC gains at higher wheel frequencies to increase disturbance rejection, thereby compensating for anti-notch filter gain reduction with increasing wheel frequency. Similar results are obtained by adding a lag-lead phase compensator filter to a resonator filter in an active ANC.
