Analytical Design of Self-Sensing Control for PMSM Using Quasi-Direct Calculation

The analytical description and parameterization of a self-sensing control (SSC) for an electrical machine is important step toward easier commissioning these systems. In this article, the advantages high bandwidth position estimation via numerical optimization filtering characteristics phase-locked loop are combined in quasi-direct (QD) calculation. QD calculation uses two parameters estimation. With help maximum possible acceleration drive train, interdependency between derived. remaining degree freedom used to tune dynamics Using transfer function estimator, which derived analytically, speed selected, specified phase-margin implemented. parameterization, no empirical or tuning needs be done, unique SSC. All results experimentally validated.
