查询词典 calculation error

A commutation error is then considered in addition to the conventional residual error to generate the innovative residual error. Such an error is applied into cost functions to derive finite impulse response and infinite impulse response filter-based adaptive algorithms for ANC applications, referred to as FxRLS/CE and FuRLS/FRE+CE algorithms, respectively. Convergence analyses based on Lyapunov stability criteria for time-varying discrete-time systems can be carried out for the FxLMS/CE, FxRLS/CE and FuRLS/ FRE+CE algorithms to ensure stability. Computer simulations and experiments demonstrate that the innovative residual error-based adaptive algorithms can free the restriction of the slow-adaptation assumption in the conventional ANC approaches.
