Nowadays, with the rapid development of high-performance servo system, As the newly rich of servo motor, Permanent magnet synchronous motor (PMSM) control requirements also become higher and higher. It is worth noting that the sensorless PMSM control system has gradually become the research hot spot. The key reason is there is a lot of inconvenience in many industrial fields to install motor speed encoder to measure the speed of PMSM (Casadei et al., 2000). For the purpose of realizing the sensorless vector control of PMSM, this study proposed a rotor speed and position estimation method based on the instantaneous power angle detection, targeted on the most common vector control method-id = 0 control algorithm. The study discussed the basic principles of the sensorless control of PMSM technology, established a PMSM sensorless vector control system simulation model. The simulation results showed that rotor speed sensorless vector control system has good dynamic and static performance and robustness characteristics. The sensorless control algorithm is simple and easy to implement.
