Abstract

The paper deals with real-time identification of the rotor parameters of the induction motor drive. The model reference adaptative control technique has been used for synthesising two identifiers. An appropriate choice of the reference model allows a Lyapunov function to be built by means of which the updating law of the rotor time constant can be found. A higher order identifier is also synthesised using the hyperstability approach which allows real-time updating of two rotor parameters. The persistent exciting property of the input vector assures the parameters convergence. Using a DSP-based system (TMS320C30), having 30 MHz clock frequency, a few experiments are conducted for testing the proposed identifiers performance in the case of a CRPWM inverter supplied drive.
