Zastosowanie rozszerzonego obserwatora stanu i parametrów do wykrywania uszkodzeń uzwojenia wirnika oraz stojana silnika indukcyjnego

In this paper possibility of application the extended state observer algorithm to rotor and stator fault detection of induction motor. The induction motor condition is analyzed using estimated rotor or stator resistance. The motor mathematical model and algorithm of extended observer are presented. Rotor and stator resistance as a additional observer element are selected. The simulations showed high accuracy and fast response of extended observer algorithm. The experimental proved theoretical assumption and demonstrated extended state observer suitability to induction motor rotor and stator faults detection.
