Optimization of Duration of Ultrashort Pulse Exciting the Spacecraft Power Supply Bus

The paper presents the circuit diagram and the parameters of the cross-section for the model of the power supply (PS) bus of a spacecraft. The optimization of the duration of an ultrashort pulse (USP) exiting the PS bus was made by genetic algorithm (GA) for minimizing the voltage maximum along the PS bus. The GA optimization was run 10 times with every set of chromosomes and populations. The graphs of results convergence are presented for every set of GA parameters. The results of these investigations may be useful for estimating the worst case of USP excitation.
