Assignment vehicle model longitudal
显示 更早的评论
Hello. When executing this script I get an error. I have no clue what I did wrong. It has to do something with "tout". The script should work together with the simulink document. In the attachment I have uploaded the assignment.

"tout" is the time ouput variable created after a successful simulation.
In your model, press Ctrl+E, make sure these two options are checked.

Yes. The simulation is not stable. You may try reducing the simulation step size but may require more understanding of the model and Simulink to make it work.
