Calculating Timing Sequence of Capacitor-Based Railgun With Given Muzzle Velocity

Electromagnetic Launcher Speed Control with a Multilevel Fast Triggering Time Algorithm (MFTTA)

“…However, I exit is not considered. Zhang et al [10] used an iterative algorithm rather than evolutionary algorithms for the TTOP. v desired is targeted.…”

“…In the VSE calculation study, a DC was applied, and the simulation was repeated for different constant armature velocities. The total resistance of the rail is calculated using the ohmic loss calculation as in (10). However, DC resistance, as stated in (9), used to isolate R vse as in (11).…”

“…However, the relation between rail current waveform and the set of triggering times in fact can be programmable in specific rail current shapes. For example, Zhang et al [10] states that for a given magnitude of flat rail current, the set of triggering time that ensures the desired rail current is unique and can be calculated iteratively. The proposed iterative algorithm is compared with GA-based solutions of TTOP, and the iterationbased method has preferable effects on calculating timing sequence [11].…”

“…The flatness of the rail current is obtained by an internal control algorithm, which reduced the optimization problem's complexity. Apart from other iterative-based solutions of TTOP in literature [10], [11], our model has an additional constraint on down-slope rail current, which reduces transition risks. Moreover, the study conducted with different capacitor voltage so that the vertex of the TTOP under given constraint is explained.…”

“…al. stated that for a given magnitude of flat rail current, the set of triggering time is unique and can be calculated iteratively [8], [9]. We also used an iterative algorithm to evaluate the set of triggering times, considering the shape of rail current and muzzle velocity [10].…”
