Question 3 a) Develop the transfer function X (s)/F(s) of the mechanical system shown in Figure 3(a). Give and explain one example the real application where you can relate with this system. (5 marks) b) Routh's stability criterion is of limited usefulness in linear control systems analysis mainly because it does not suggest how to stabilize an unstable system. Thus, we should evaluate the stability range of a parameter value. Consider the servo system with tachometer feedback as...
Please make sure your answer is correct. I have gotten numerous
wrong answers. Thanks.
This one too:
And this one:
Again please make sure you are correct.
If you have time: This one was marked wrong too, so if you can
solve I give thumbs up thanks.
