Abstract

Nanosateliti se sastoje od različitih podsustava i jedan od najbitnijih, koji je odgovaran za cjelokupnu funkcionalnost satelita, je električni podsustav. U ovom radu razvijen je koncept sustava napajanja u razvojnom okruženju Simulink. Demonstrirana je funkcionalnost algoritma i problemi koji su prisutni pri realizaciji električnog podsustava, poput male efikasnosti solarnih panela, potrebe za usklađivanjem naponskih razina te nesavršenosti upravljačkog algoritma. Kako bi se model mogao koristiti komercijonalno ili u ozbiljnije svrhe potrebno je potpuno optimizirati model, ubrzati simulaciju te izgladiti prijelazne pojave.

Abstract (english)

Nanosatellites consist of different subsystems and one of the most important one, which is responsible for the overall satellite functionallty, is the electrical subsystem. In this paper, the concept of power supply system is developted in the Simulink enviorment. The functionality of the algorithm and the problems that are present in the realization of the electrical subsystem, such as low efficiency of solar panels, the need to adjust the voltage levels and the imperfection of the control algorithm are demonstrated. In order for the model to be used commercially or for more serious purposes, it is necessary to fully optimize the model, speed up the simulation and smooth out the transients.
