Owing to the competitive advantages of cost reduction, system downsizing, and reliability enhancement, position sensorless control methods for permanent magnet synchronous machine (PMSM) drives have drawn increasing attentions from academia to industry applications. In this paper, a survey of the major sensorless control techniques for a wide speed range fromlow to high speeds is presented. The different high frequency (HF) signal injection schemes, fundamental PWM excitation methods, and model based sensorless control are displayed and compared, which is able to facilitate the sensorless control implementation.
