42: Consider the dynamic system that is represented by the transfer function G(s) (s+a) (s+b)(s-c) and a compensator defined by, illustrated in the figure (s++) below. Determine:Gr(s) = Kc (s+=) a) The parametric ratio that must be respected to ensure closed-loop stability. b) Get the place of the related G(s) roots, considering the values of the defined parameters, and par with the particular case where Gr(s) 1.
