Estimation Algorithm Non-Stationary Frequency of the Sinusoidal Signal

  title={Estimation Algorithm Non-Stationary Frequency of the Sinusoidal Signal},
  author={S. I. Nizovtsev and Sergei V. Shavetov and Anton A. Pyrkin},
The article considers the problem of identifying the variable frequency of a sinusoidal signal. To obtain a regression model of the signal, an iterative differentiation of the original analytical expression is performed, and the swapping lemma is applied. The estimation of the parameters of the non-stationary frequency is implemented using the dynamic expansion of the regressor and mixing (DREM) procedure and the Luenberger observer. As a result of the numerical simulation, the efficiency of… Expand


Finite Time Frequency Estimation for Multi-Sinusoidal Signals
A method to estimate frequencies of a multi-sinusoidal signal in finite time by transforming this nonlinear problem into a linear regression, where unknown parameters depend on signal frequencies. Expand
The multi-harmonic signal frequencies estimation in finite time
The paper presents a method to estimate the frequencies of a multi-harmonic signal in finite time. We use parameterization based on applying delay operators to a measurable signal. The result is aExpand
DREM-based Parametric Estimation of Bias-affected Damped Sinusoidal Signals*
The Dynamic Regressor Extension and Mixing (DREM) method is used to replace third order regression with three first order regression models, where simple relaxation is applied to provide exponential convergence of the estimation error to zero. Expand
A parameter estimation approach to state observation of nonlinear systems
The proposed approach is shown to be applicable to position estimation of a class of electromechanical systems and to two assumptions related to solvability of a partial differential equation and the ability to estimate the unknown parameters. Expand
Adaptive state observers using dynamic regressor extension and mixing
This paper proposes an adaptive state observer for a class of nonlinear systems with unknown parameters and uses the recently proposed dynamic regressor extension and mixing approach, whose main feature is that it allows to generate, out of an N -dimensional, linear vector regression, N scalar regression models.
