Answer #1

The question is not clear enough so I tried the question with two different transfer functions.

G(s)=(s-3)/ s(s+2) System has positive pole and positive zero. im trying to nyquist plot by hand, G|jw|=0.5 i found but matlab says GM=infinity. Can you explain please? And i wrote phase like this= -90-arctan(w/2)-arctan(-w/3) is this true? Because I found -148+180 = 32 degree PM but Matlab says : PM= -148 degree. Thanks for your help.

Consider the nonlinear second-order differential equation 4x"+4x'+2(k^2)(x^2)− 1/2 =0, where k > 0 is a constant. Answer to the following questions. (a) Show that there is no periodic solution in a simply connected region R={(x,y) ∈ R2 | x <0}. (Hint: Use the corollary to Theorem 11.5.1>> If symply connected region R either contains no critical points of plane autonomous system or contains a single saddle point, then there are no periodic solutions. ) (b) Derive a plane autonomous system...
