Abstract :
This paper deals with the problem of parameter adaptation in feed-forward field-oriented induction motor drive systems. The MRAC method is employed and d-axis voltage, q-axis voltage and reactive power algebraic reference models are analyzed. Adaptation error expressions are derived showing a dependence on torque current transients. A dynamic model for the induction motor under field orientation which predict both its transient and steady state behavior is presented. Based on it d-axis voltage, q-axis voltage and reactive power dynamic reference models are derived. Simulation results show a performance increasing through q-axis voltage and reactive power dynamic reference models while remain unchanged for d-axis voltage reference model
