P6.6 A unity-feedback control system is shown in Figure P6.6 ?. Determine the stability of the system with the following loop transfer functions using the Routh-Hurwitz criterion: a. Gc?(s)G(s)=s2(s+4)2s+2? b. Gc?(s)G(s)=s(s3+10s2+35s+75)30? c. Gc?(s)G(s)=s(s+4)(s+7)(s+1)(s+3)? Figure P6.6 Unity feedback system
