摘　　要：针对实际应用中,有源噪声控制系统中噪声信号的周期存在小范围波动,从而带来标准重复控制系统降噪不够理想的问题,提出采用基于多环的鲁棒重复控制算法。并将该算法与标准重复控制算法在频谱、残余误差、收敛速度方面进行比较。仿真结果表明,当噪声信号周期有小范围波动时,鲁棒重复控制算法有良好的降噪效果。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 memory- loops. 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.
