This invention discloses a direct control method for torque and axial force of a linear rotary switched reluctance motor. First, the sector containing the flux linkage vector is determined through calculation. Based on the flux linkage hysteresis signal and the torque hysteresis signal, the voltage vector required for control is determined. Then, the axial force is controlled within the control range of (-15°, 15°) where the rotor position is selected. The corresponding axial force voltage vector is selected based on the axial force hysteresis signal. Finally, the operating mode of each power converter switch is determined based on the signs of all voltage vectors. This invention significantly reduces torque and axial force pulsation by directly controlling the motor's torque and axial force, resulting in a faster system response. Operating modes for the torque winding and axial force winding are established separately for torque and axial force, respectively, leading to more reasonable vector selection. Furthermore, no model calculation is performed during the control process, so the control accuracy does not depend on the analytical model, improving the system response speed and simplifying the control strategy.
