Sensorless Control of a Permanent Magnet Synchronous Motor Based on Direct Compensation in a Current Loop

The paper is devoted to the development of an original method for estimating the permanent magnet synchronous motor rotor angular position. The study considers a vector control system with tuning of the current loop to the desired transfer function with linearization and active damping. An adaptive state observer the adaptive model of which receives signals from the internal variables of the vector control system current regulator of permanent magnet synchronous motor is described. The specifics of realization of sensorless control systems are described. The results of system simulation are given.
