Abstract:
Currently， the axial motion of linear-rotary switched reluctance motor （LRSRM） can only achieve axial positioning， and the two-degree-of-freedom motion is simple. A linear-velocity control method is proposed in the paper to improve the axial control performance. The axial displacement and velocity of rotor are controlled by linear position/velocity observer. The torque winding current and axial-force winding current are calculated by the mathematical model of torque and axial force， and then distributed to the corresponding conducted region for current hysteresis. It can effectively regulate the axial velocity and displacement of the rotor during the rotation process. The effectiveness and accuracy of the proposed method are verified by simulation and experiments.
