Abstract :
The influence of the rotor time constant mismatch on the stability of induction motors under indirect field-oriented control is analyzed. The paper focuses on the global asymptotic stability property and extends previous results of the authors´ (1998). A global stability criterion based on the solution of an LMI problem is given. Robustness margins for global asymptotic stability with respect to rotor time constant mismatches are obtained using this criterion
