摘要：

A simple linear tracking-differentiator is proposed and the convergence proved for any differentiable signal with random perturbation to be tracked. This enables us to design a relatively simple globally convergent online estimator of the frequency of a sinusoidal signal under small random perturbation. The polynomial convergent rate is obtained.
