A trigonometric velocity estimator using a resolver sensor in drive system applications

Paper in proceeding, 2012

Resolver sensors are widely used in the industry to measure the rotor angle position in high performance drive applications. Different methods are employed to estimate the velocity by measuring the rotor angle position. A novel trigonometric velocity estimator is described in this paper that has a simple structure for implementation and there is no need for parameter tuning. The proposed method is practically verified in a permanent magnet motor drive system. The results confirm that the proposed trigonometric velocity estimator has a good dynamic and steady state response subjected to different speed command profiles.
