1. The transfer function, G(s) of a control system is given as 10 G(s) = s(0.1s + 1)(s + 1) The closed-loop stability of above system can be easily analyzed using Bode plot technique. The following steps are the typical procedure to establish the Bode plot; Normalized transfer function: G(s) = The break frequencies: wf = 1,10 rad/s Starting frequency: one decade of minimum w: 0.1 rad/s Gradient table of Magnitude and Phase: Pole/Zerowat Sp₂ = -1 S3 = -10 Total Gradient Pole/Zero waT Sp2 = -1 Spa=-10 Total Gradient Wat = 0.1 10 s(0.1s + 1)(s + 1) Way = 0.1 Magnitude gradient war = 10 Why = 1 Way = 1 Phase gradient Way = 10 way = 100 Wy=100
