The utilization of Levenberg-Marquardt's method (LM) for the identification of an unknown model parameters of the electronic current transducer with a Hall effect sensor in the negative feedback loop has been described. The saturation reasons of the electronic block in the transducer model have been also taken into consideration which made it possible to use the model in error analysis of the electronic transducer while deformed signals are being measured in the power electronics and automation.
