You are using a proportional control Gc-Kc for a feedback control of a process with Gv=4/(2s+1), Gp=0.6/(50s+1), and Gm=2/(taus+1) (time constant in seconds). Determine the range of Kc that the feedback loop can stay stable for tau=1 and tau=20, respectively.

(a) Using the Routh Array approach

(b) Using the Root Locus approach

(c) Using the Frequency Response approach

Are the results from (a)-(c) consistent with each other?
