Abstract

This paper presents a new method for the real-time estimation of the parameters and fluxes of induction motors. Such a procedure is useful for the design of self-commissioning drives, i.e., drives that can adjust controller parameters automatically for a wide range of motors and loads. Another potential application is for the diagnostic of failures. In their recursive form, the algorithms can be used for adaptation to parameters that vary with time, and for estimation of the rotor fluxes in a field-oriented controlled drive. The estimation method is based on a standard model of the induction motor, expressed in rotor coordinates. It is assumed that current and position (or velocity) measurements are available. The rotor fluxes are not assumed to be measured. The interesting features of the method are that: 1) it does not rely on special tests such as the locked rotor test or the no-load test (instead, a broad range of motor responses can be used), 2) the method provides estimates of the rotor fluxes together with the estimates of the parameters, 3) measures of the uncertainties in the estimated motor parameters are provided (this provides feedback as to the precision of the parameter estimates, as well as some guidance to choose excitation and to optimize the quality of the parameter estimation). Results for both simulated and experimental data are provided.
