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.]]>Bolognani, S., L. Tubiana and M. Zigliotto,20033917411747Li, C. and M. Elbuluk,20012001pp: 12731278Casadei, D., G.
