【Abstract】 Due to narrow dynamic range and weak real-time track capability of adaptive algorithm in active control of noise,an improved adaptive algorithm with the multi error improved normalization and variational step size is investigated.The parallel on-line modelling method is discussed in details,so at to solve the key problems of active control of noise.更多还原
