Linear prediction and compensation control of roll eccentricity based on cyclic statistics

The concept of the characteristic curves of roll eccentricity was proposed. Based on cyclic statistics of the tested signal, a linear prediction model was established to on-line determine the compensation data of roll eccentricity for realizing the real-time compensation control of roll eccentricity. Simulation results show that the method can accurately trace roll-eccentricity-induced disturbances and meet the needs for real-time compensation for the control of roll eccentricity.
