Sensorless Control of a Linearized and Decoupled Induction Motor Drive
نویسندگان
چکیده
This paper presents an input-output linearizing and decoupling control scheme with speed estimation for an adjustable speed induction motor drive. A stator flux based estimator is used to estimate the synchronous speed. The motor speed is estimated by measuring only two line currents and two line voltages. A moving average algorithm is used to filter the ripples in the estimated speed. Simulation studies show that the sensorless speed control scheme can achieve fast transient response and maintain a wide speed control range.
