摘要

给出了在给定辨识精度下保证有限收敛时间的频率估计技术。提出了一种抑制高频噪声的方法。讨论了引入切换算法提高估计质量的可能性。所提出的解是3阶的,比其他已有的解要小。计算机仿真实例验证了该方法的有效性。

Frequency estimation for periodical signal with noise in finite time
The frequency estimation technique with guaranteed finite time of convergence to a given accuracy of identification is presented. The approach for a high frequency noise rejection is proposed. The possibility of switching algorithm introduction for estimation quality improvement is discussed. The proposed solution has order three, that is smaller than in other existent solutions. Efficiency of the approach is demonstrated on examples of computer simulation.
