Abstract
Real-time identifiers of the rotor parameters of induction motor drive are presented in the paper. The synthesis procedure of the identifiers is based on the MRAC System Theory. An appropriate choice of the reference model allows to build a Lyapunov function by means of which the updating law of one of the above mentioned parameters can be found. Higher order identifier is also synthesised using hyperstability approach which allows realtime updating of two rotor parameters. The parameters convergence is assured thanks to the Persistent Exciting propriety of the input vector. A DSP-based system (TMS320C30), having 30MHz clock frequency, is used for testing the proposed identifiers in a CRPWM inverter supplied drive| File | Dimensione | Formato | |
