I am trying this from a book entitled "Control Engineering: An Introductory Course" and encountered the problem below (with solutions). The issue is I do not understand the solution, mind explaining to me (I will elaborate my questions after the screenshots)?

Heres the question, how can i get the graph as in Figuew 18.11? I have setup the Simulink as in fgure 18.10. For the transport delay under the time dlay parameter, what unit is used by Simulink? I entered 0.15. But I have yet to get the graph in Figure 18.11. Any help? Thanks

BTW, 2018a user.

To get the plot in your shown figure, you should run your simulink model that gives the data (ytemp from simout block) into matlab workspace. You can plot ytemp against time.
An alternative way is if you can use MATLAB, just create a transfer fucntion and use lsim() function. With the graphical plot tools of lsim(), you can easily find out overshoot, settle time, rise time, etc.

Good luck
