MOVER POSITION AND SPEED ESTIMATION FOR LINEAR SYNCHRONOUS MOTOR BASED ON SALIENCY-TRACKING METHOD
Saliency-tracking self-sensing method was applied in this paper. The method was based on high-frequency voltage signals injection. Three-phase symmetrical high-frequency voltage signals were added to the system before SVPWM regulator, which produced high-frequency current signals containing positive component and negative component. The negative component included position and velocity signals of the mover. Position and velocity signals could be extracted from negative current component by rotating vector, filter and heterodyning tracking observers. All process was discussed in detail in this paper. The simulation results of a instance verifies the correctness and availableness of this method.Furthermore, merit and limitation of this method can also be mentioned in this paper.
