A STUDY ON THE BEARINGLESS MOTOR FOR A SYNCHRO ULTRA-HIGH-SPEED CAMERA

Bearingless motor is a nonlinear multivariable system with a strong coupling In this paper, a decoupling control approach has been developed for a bearingless motor to drive a synchro ultra high speed camera A nonlinear controller based on dynamic feedback linearization is designed such that the nonlinear system with strongly coupled motion is reduced to four decoupled normalization linear subsystems, including two rotor displacements and its speed as well as rotor flux Linear system theory is utilized to improve the transient performance of these normalization linear subsystems To verify the effectiveness of the control scheme, some simulations have been employed, and satisfactory performance of the decoupled system is obtained
