Hi,
  • This model is identified online (or on-line)?
  • This model is built by using an online (or on-line) identification technique.
  • The ship sails along a straight line (or straight-line).
  • A straight line (or straight-line) tracking control method is proposed.
I am not sure if there are some differences between them.

Thanks for answering.
