摘要:在建立自适应陷波算法的离散系统状态空间方程的基础上,提出了收敛速度和稳态误差两个评价指标,推导出了收敛率和稳态误差增益的计算方法,并针对收敛系数、陷波频率数、通道数、次级通路特性与参考信号特性对收敛速度和稳态误差的影响进行了分析。最后通过实验对仿真结果进行了验证。



Abstract:Based on the state space equation of the discrete system with the adaptive notch algorithm, two evaluation indexes of convergence speed and steady-state error are proposed, and the calculation methods of convergence rate and steady-state error gain are deduced. Moreover, the effects of convergence rate, notch frequency, number of channels, secondary path characteristics and reference signal on convergence rate and steady-state error are analyzed. Furthermore, the simulation results are verified by experiments.
