Matlab Simulink power supply

Hello, I faced a problem during implementation of 24 V Dc power supply in simulink. I would like to share my question here. I added a step source which rises up to 24 V directly and ideally, however in reality it gives out fluctuations in the beginning<in my opinion the power source is not so strong>Does anyone have any idea how to implement this behaviour ? It is an power supply where the voltage is from 230V AC to 24 V Dc converted.

If you have an idea about the fluctuations, they are probably aleatory. You can use a random source, like a Band-Limited White Noise block to generate random signal and add it to the output of your source
