Space modulation profile modelling for steer‐by‐wire SMPMSM

Abstract

This paper presents a sensorless estimation algorithm for steer‐by‐wire applications based on the injection of a high‐frequency rotating voltage. Enhancement to the basic sensorless algorithm through SMP look‐up tables is proposed. The improved observer was simulated in MATLAB for a 12 V RMS 400 W permanent magnet synchronous machine (PMSM).
