Abstract
The paper deals with the problem of position and speed estimation methods
in SRM (Switched Reluctance Motor) drive equipped with hysteresis band
current controller with MRAS (Model Reference Adaptive System) type
observer. An adaptive flux model uses equation set of one-dimensional
equations instead of one two-dimensional equation. The reference model is
the formal one. Instead of measured current the observer utilizes
reference current. Such drive system works well at speed range up to 600
rad/s. The observer's gains must change depend on the speed range. The
robustness on motor parameter poor estimation is presented.
