摘      要：The characterization of sinusoidal signals with time varying amplitude and phase is useful and applicable for many *** several algorithms have been suggested to estimate main aspects of these *** no standard approach to test the properties of these algorithms,it seems to be helpful to discuss a large class of algorithms according to their *** this paper,six methods of estimating dynamic phasor have been reviewed and discussed which three of them are based on least square and others are based on Kalman *** expansion is used as a first step and continued with least square or Kalman filter in accordance with the proposal observer of each *** theoretical processes of these methods are briefly *** characterizations have been made by some tests in time and frequency *** tests include amplitude step,phase step,frequency step,frequency response,total vector error,transient monitor,noise,sample number,computation time,harmonic and DC offset which build a framework to compare the different methods.
