| Abstract |
The application of vector control techniques in a.c. drives
demands accurate position and speed feedback information for
the current control and servo-control loops. The paper describes
al sensorless speed digital control system for interior permanent
magnet synchronous machines (IPMSM). A Kalman filter is
used for the mechanical state estimation of the motor. The
observer was developed based on non-linear model of the
synchronous motor that employs a q d − rotating reference
frame attached to the rotor. The control system includes a rotor
frame vector current controller with feed-forward decoupling
circuit and an integral+integral proportional (I + PI) speed
controller. |
