Question 3 a) Develop the transfer function X2%)/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 shown in Figure...
