A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

Abstract: The traditional DTC method directly controls the torque and flux linkage without model calculation, which is beneficial to restraining torque ripples. However, the LRSRM not only provides ...

Abstract: A robust mechanical parameter estimation together with adaptive speed control algorithms for permanent magnet synchronous motor (PMSM) drive systems based on the dual adaptive sliding-mode ...
