hello,guys i have learned how to model a e-auto. the webside is https://www.mathworks.com/videos/formula-student-physical-modeling-training-part-5-vehicle-drive-and-control-107488.html. From this video I have found a problem. When I build a DC-DC Converter(Block:ideal Transformer, ratio:0.5) between battery and PWM Average, the scope of the speed is not constant after 30sec. my question is how to make the speed constant after 30sec.

Hello Jianghui Xu,
my name is Christoph and I have been in the team that has developed this course. Great to hear that it is helpful to you.
To answer your questions:
We have on purpose given certain inputs to the car, such as a speed reference, gear shift and brake actions, in order to show how it behaves. If you want to assign your own 'driving commands' to the car, please edit the following block (see also figures attached):
Does that help you?
Cheers Christoph
