The invention discloses a current-position-based switched reluctance motor torque pulsation suppression method and system. According to the method, the sum of square of phase current is calculated directly by a rotor position angle based on a current-position neural network model to be used as the reference total current; a three-phase reference current is obtained through a distribution function; and the difference between the three-phase reference current and a three-phase actually-measured current is used as an input signal of a current lagging controller to control the operation of the switched reluctance motor. A system signal processor is connected with a current sensor, a torque sensor and a position sensor to receive a signal; and the current-position neural network model and a current distribution module performs calculation to obtain the input signal of the current lagging controller to control a power driver to drive the SRM. According to a periodical relation between the sum of square of phase current and the rotor position angle, the current-position neural network model is designed, so that the torque pulsation of the SRM is effectively lowered.
