Aiming at the fast response of attacking target for the electromagnetic rail launcher system（ EMRLS） ,a quick solu-tion method of discharge sequence of pulsed power before launch with steady acceleration was proposed.First,considering the system characteristics of high voltage,large current and heavy load,the conditions of steady acceleration were analyzed and its realization method was proposed.Secondly,a model for expressing the exit velocity of the projectile with discharge sequence of the pulsed power modules was established under the conditions of steady acceleration for the EMRLS,which includes relational data tables and re-sponse surface model.On the basis of constructing the model,an acquisition method of discharge sequence of pulsed power before launch was given.Finally,the proposed method was applied to solving the discharge sequence of pulsed power modules for an EM-RLS.The simulation results show that the method can reduce the computation time significantly and achieve the steady launch,which validate the availability of the method.
