Projectile speed control method and device for rail type electromagnetic launcher and electronic equipment

The invention discloses a projectile speed control method for a rail type electromagnetic launcher. According to the method, a power supply comprises multiple pulse power modules. In the multiple pulse power modules, the first-class pulse power modules which are started initially and the second-class pulse power modules which are controlled to be started are included. The method can comprise the steps that after the first-class pulse power modules of the power supply are started to trigger projectile starting and launching, the detection speed generated when a projectile passes through a preset detection position of a rail of the rail type electromagnetic launcher is obtained; according to a pre-established relational expression between the speed generated when the projectile passes through the preset detection position and the starting moment of the second-class pulse power modules, the actual starting moment of the second-class pulse power modules is calculated based on the detectionspeed; and when the actu
