Bottom Line: Either the motor design or the motor control needs to be improved in order to minimize the periodic disturbances.The compensating signal is identified and added as feedback to the control signal of the servo motor.Compensation is evaluated for different values of the input signal, to show robustness of the proposed method.

ABSTRACT
A persistent problem of surface mounted permanent magnet (SMPM) motors is the non-uniformity of the developed torque. Either the motor design or the motor control needs to be improved in order to minimize the periodic disturbances. This paper proposes a new control technique for reducing periodic disturbances in permanent magnet (PM) electro-mechanical actuators, by advancing a new observer/estimator paradigm. A recursive estimation algorithm is implemented for online control. The compensating signal is identified and added as feedback to the control signal of the servo motor. Compensation is evaluated for different values of the input signal, to show robustness of the proposed method.

Mentions: In Fig 15, considering an excitation signal of 7V (arbitrary chosen), frequency spectra of the current are compared before and after the compensation. Here it can be seen that harmonics 1, 3, 4, 5, 7, 8, 16 are suppressed without inserting any additional noise.
