DC motor parameter identification using equation error method

Abstract

The paper deals with the identification of a direct current motor using experimentally measured transient processes of the motor starting and running-down at a no-load driving torque. The identification is based on the equation error method, which was chosen for its ability to work with noisy data. The major point of the method is that the data of the experimentally obtained measurements are reciprocally associated with the differential equations defining the analysed object. The paper discusses the process and the results of identification.
