Transient damping torques in synchronous machines during disturbances

Proceedings of the Institution of Electrical Engineers, 1969
During power-system disturbances, the relative speed between the resultant flux and the rotor causes eddy currents to be induced in the rotor iron structure and an induction-motor or induction-generator torque to be developed owing to the amortisseur winding; both these effects damp out the synchronousmachine oscillations.

Adaptive feedforward control for disturbance torque rejection in seeker stabilizing loop

IEEE Transactions on Control Systems Technology, 2001
Important sources of disturbance torque inputs, which may severely degrade the seeker tracking accuracy of a guided missile, involve seeker mass imbalance, seeker gimbal friction, and seeker head restoring torque. The paper presents an approach to treat the disturbance rejection problem for the missile seeker.

Drive induced torque disturbances in brushless rate servos

Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting, 2002
The torque disturbances caused by imperfections in a permanent magnet brushless sinusoidal motor and sinusoidal power amplifier are discussed, and the major sources of disturbances are quantified. Brushless rate servos are shown to contain many new sources of torque disturbances, in addition to the disturbances produced by brush type rate servos.

Analysis of estimation error of observer for disturbance torque and velocity

Electrical Engineering in Japan, 1994
AbstractThis paper analyzes some features of estimation error of the observer which estimates disturbance torque and velocity. This observer inputs the information of driving torque and current position, and outputs the information of disturbance torque and velocity.Although this observer is a practical tool to compose a robust control system, there ...
