In the present paper, a force distribution function is used to control and reduce ripple and inherent fluctuations in output force of segmental translator linear switched reluctance motors (STLSRM). The turn-on and turn-off angles are the important control parameters for the force distribution functions and proper selection of them has significant effect on increasing and decreasing effectiveness of the function used for reducing the force ripple. In order to determine the proper operation position of each switch, two control algorithms are proposed in this paper. When changing motor operating point, online calculation of the optimum turn-on and off angles is done using the proposed algorithms and the obtained values are used for force distribution function to make the reference force profile. The proposed algorithms have a significant impact on reduction of force output ripple and copper losses and increase of the motor efficiency. The effectiveness of the proposed control methods in control of the motor performance to reduce inherent force ripple and copper losses is evaluated using the simulation results given for a typical motor.
