State and Parameter Estimation Methods for Sensorless Drives
CURRENTLY, SPEED OR POSITION SENSORLESS DRIVE becomes crucial in industries in order to increase mechanical robustness and reliability of overall system in addition to decrease of its cost, size, and hardware complexity. However, the performance of sensorless control of electrical motors directly depends on the performance of states/parameters estimations, which is still problematic due to uncertainties in model, errors in measurements, variations in model parameters, and losing stability or observability around zero-speed range. Therefore, a great effort is needed in the literature to enhance the estimation performances of the states/parameters. This effort can be classified as deterministic and stochastic based estimator or observer designs utilizing two-phase electrical motor model in addition to non-model based high-frequency signal injection techniques. Purpose of this Special Section is to reveal the most recent findings to solve the problems associated with the sensorless estimation methods, and thus high-performance and efficient sensorless electrical drives. The papers to be prepared for this Special Section must include original materials that has not been submitted to or published in any other journal. Academicians and Practicing Engineers all over the world are invited to submit their recent original research contributions to this Special Section.
