| Abstract |
This paper presents a sensorless vector control method for permanent magnet
synchronous motors based on a reduced order observer. This observer estimates only mechanical
variables of machine, speed and rotor position. To converge the estimated values to their real ones, the
observer uses electromotive force components in park frame. These components could be calculated
using machine model and electrical variables.
This method permits to start up from an unknown initial position and control the motor in transient
and steady state. This approach has been simulated and implemented in a test bench. Simulation and
experimental results illustrate the validity of the proposed method. |
