| Abstract |
To solve the instability problem of the adaptive observer based sensorless drive, stability conditions
of the speed estimation are analytically derived, and a novel design of feedback gains of the observer
is proposed to restore the stability for the whole operation especially in the low speed region,
including the regenerating mode. Stability improvement using the proposed feedback gains is
rigorously proven by the method of Lyapunov. The validity of the theoretical results is verified by
simulation and experiment. |
