Abstract
A new approach in design an efficient algorithm for ANC system is proposed. The transversal filter-based controllers (FIR and IIR) are first considered. A Lyapunov function of the error is first defined and filter coefficients are then adaptively adjusted based on Lyapunov stability theory so that the error converges to zero asymptotically. The design is independent of the statistic properties of signals and its computation complexity is comparable to FXLMS. It has fast error convergence properties and the stability is guaranteed by Lyapunov stability theory. This scheme can be further extended to an efficient nonlinear ANC using RBF network for excellent performance. Simulation examples are demonstrated to show the degree of noise cancellation this scheme can achieve.
