Abstract

In this paper, we present a methodology for the design of a speed sensorless flux observer for induction motors using a behavioral model of the angular speed. We start by developing a reduced order model of the induction motor using complex differential equations. After that, we formulate a behavioral model whose data represents the angular speed of the physical model of the induction motor. This has been done because the original equation governing the rotor speed within the physical model of the machine is highly nonlinear and too complicated to analyse. Furthermore, we use the developed behavioral model in order to design the speed sensorless flux observer for induction motors. The validity of the proposed approach is verified from simulation of the model of the induction motor's flux observer.
