Simulation time on Simulink
显示 更早的评论
Hi people... For exemplo, if my simulation time in simulink is 10, this represents 10 realy seconds?

You set the start and stop time of your simulation model. If you set the start time to be 0, and the stop time to be 10 and then click the "Start Simulation" button. It might take just 0.1 second to finish the simulation, or it might take 1 hour. It depends on how complex the model is, what is your simulation solver setting and what is your computer CPU power, etc. The Simulink software just generates the clock from 0 to 10 seconds and calculates every bit of data needed at every time step that you set up.

I am not clear what do you mean. If you have a mathematical model of your battery which changes as time goes, then a day has 24*3600 seconds.

It depends on your model in Simulink. If the model is constructed to describe the behavior per hour, then you just need to set the stop time to be 24. It is simulating a discrete event, one per hour. If the model is based on minute, then 24*60. You have to have the understanding of your model.

I don't know the details but I can't imagine the model is described "per day". If you are talking about charging a battery using solar power, I would think it needs to be modeled per hour at least. The radiation is different in the morning, noon, afternoon and night, right? Unless you are analyzing the solar energy year-around and you are only interested in the solar energy in summer days or winter days. Again, you need to dig deep in your model. This question is better to ask yourself or seek help from whoever knows your model.
