A RMRAC parameter identification algorithm applied to SPIM

This paper presents a closed-loop automatic method able to identify all electrical parameters of single phases induction machines. The system is based on Robust Model Reference Adaptive Controller that is applied at qd axes machine model. The identification procedure is based on currents measurements with standstill rotor and is divided in two times: in the first time, all parameters of main winding are identified and, in the second time, the parameters of auxiliary winding are identified. From the obtained parameters it is possible to design high performance controllers and sensorless control for single phase induction motor. Furthermore, was observed that the obtained parameters allow a better representation of dynamic simulation behavior of machine and performance calculation. Simulation and experimental results are presented to provide the effectiveness of the method.
