Unformatted text preview: the form D(s) = feedback structure. K ( s + a) in series with G(s) in a unity( s + b) (1) Ignoring stability for the moment, what are the constraints on K , a, and b so that the system is Type 1? (2) What are the constraints placed on K , a, and b so that the system is both stable and Type 1? 35. Consider the transfer function 1 s2 + s + 2 H (s) = Which of the following is the corresponding unit step response? Explain your choice and why you rejected the other three possibilities. (a) (b) 0.7 (c) 0.8 0.6 (d) 1.4 1 1.2 0.6 0.5 0.8 1 0.4 0.4 0.8 0.6 0.3 0.2 0.6 0.4 0.2 0.4 0 0.1 0 0 5 10 −0.2 0.2 0.2 0 5 10 4 0 0 5 10 0 0 5 10...
