SAW torque transducers for disturbance rejection and tracking control of multi-inertia servo-drive systems [PDF]

, 2004
The paper proposes a resonance ratio control (RRC) technique for the coordinated motion control of multi-inertia mechanical systems, based on the measurement of shaft torque via a SAW-based torque sensor. Furthermore, a new controller structure, RRC plus

An Adaptive Harmonics Suppression Strategy Using a Proportional Multi-Resonant Controller Based on Generalized Frequency Selector for PMSM

Actuators
In permanent magnet synchronous motor (PMSM) drive systems, the nonlinearity of the inverter and non-sinusoidal nature of back EMF generate harmonics in the stator current, resulting in torque ripple and reduced motor efficiency.
