Abstract
Accurate measurement of rotor angle in Permanent Magnet Synchronous Motor (PMSM) drive applications is important when high performances as low level torque ripples are required. If the relationship between torque ripple and angle error is known, then, further steps can be done in order to reduce the level of the ripple. Based on an analytical description of the sensor model, a relationship between the angle error and speed error (seen as a noise source for the system) as well as torque ripples are deduced. Simulation results for a specific range of mechanical speed using SystemC-AMS models confirm the theoretical analysis.
