The invention belongs to the technical field of nonlinear hysteresis system modeling and controlling and discloses a reluctance actuator electromagnetic force modeling and motion controlling method. The method comprises the following steps: (1) establishing a first-generation positive-and-negative hysteresis analytical mathematical model; (2) using a shape correcting function to optimize the first-generation positive-and-negative hysteresis analytical mathematical model to obtain a positive-and-negative hysteresis analytical mathematical model; (3) according to Amps law, establishing a magnetic circuit calculating formula and in combination with the positive-and-negative hysteresis analytical mathematical model, inferring the reluctance actuator electromagnetic force calculating formula with the consideration of the hysteresis effect and the mathematic expression of the positive-and-negative hysteresis analytical mathematical model between the electromagnetic force and the current; and (4) in combination with the obtained mathematical expression between the electromagnetic force and the current, using the displacement-force-current multi-loop series motion control to the reluctance actuator. The above method considers the influence of hysteresis non-linearity on the control of the reluctance actuator, improves the precision, and has a wide range of use, which is favorable for popularization and application.
