PARAMETRIC AND NON-PARAMETRIC CHARACTERIZATION OF AN INDUCTION MOTOR USING THE HARTLEY SERIES

In this paper, a novel technique for on-line estimation of most electrical parameters of an induction motor is presented. Such estimation is important to achieve high performance drive systems. The proposed technique uses Hartley Series. This technique is based on the measurements of the stator voltages, currents and motor speed with no need for state-space modeling. Moreover, the Hartley Series is implemented to relate the steady-state performance characteristics of an induction motor to their inputs. Simulation and practical results establish the validity of the proposed technique and show reasonable accuracy of the estimated parameters as well as excellent steady-state performance characteristics.
