Hunting is a flutter associated with the synchronous speed that gives rise to the
gyro drifting errors and may cause objectionable time-displacement errors in video head
wheel drives and other precision scanning systems. In this paper, dynamic characteristics of
permanent Magnet hysteresis motors are presented and hunting is explained. New damping
techniques have been developed using optimized eigenvalues calculation. They are
calculated from LQR optimization method. In this damping method, a distinct reduction in
hunting has been archived. Furthermore field oriented control result of motor is presented
that have good effect on Hunting. Nearest agreement between simulated and measurement
results shows the accuracy of motor model. Comparison between this paper results and
other measured damping methods result are shown its success.
