Abstrac: This papers deals with the use of a Model of Reference Adaptive Control (MRAC) scheme for parameter adaptation of an indirect field oriented control of an induction motor. The behavior of the parameters was analyzed using three different reference models. The considered reference models were: direct axis voltage(d), quadrature axis voltage (q) and reactive power. For each reference model the adaptation error was analyze. Using the obtained equations the parameter convergence in different motor conditions was analyzed.

Resumen: Este trabajo trata sobre la utilización de un esquema de Control Adaptable por Modelo de Referencia (MRAC) para la adaptación de parámetros de un control indirecto por campo orientado de un motor de inducción. Se analiza el comportamiento de los parámetros utilizando tres modelos de referencias distintos. Los modelos de referencia considerados fueron: voltaje en el eje directo (d), voltaje en el eje en cuadratura (q) y potencia reactiva. Para cada modelo de referencia se desarrolló el error de adaptación. A través de estas ecuaciones se analizó la convergencia de parámetros en diversas condiciones del motor.
