Abstract :
This paper studies the parameter sensitivity of the dq-voltage and reactive power models, used in the MRAC strategy for tuning the indirect field oriented controller (IFO). This study is evaluated at different speed and load conditions. Based on the results, a scheme for on-line estimation of the parameters that influence the reference models is proposed. A procedure for estimation of rs and σls is proposed. This makes the MRAC more robust. Simulation and experimental results are present
