Control systems. First, second, third and fourth order systems

Graph for each order model. 1-4.

And then 4 graphs for third order model which helps to answer the last question.

For the 3rd order model, get the graphs of the output response and comment on the performance of the system (for various values of Kt , e.g. 0.05, 0.1,0.3 and 0.5) (Graphs of these will be provided)

Discuss the effect of the velocity feedback on the system (in depth analysis of system stability)
