Abstract
To solve the noise reduction performance problem of an active noise control(ANC)system based on standard repetitive control algorithm when the period of noise signal changes slightly in the practical application,a robust repetitive control algorithm is proposed based on multiple memoryloops.The algorithm is compared with standard repetitive control algorithm from the aspects of spectrum,residual error and convergence speed.Simulation results show that the ANC system based on robust repetitive control algorithm has better canceling performance when the period of noise signal changes slightly.
