Two engineers are analyzing step-test data from a biore-actor. Engineer A says that the data indicate a second-orderoverdamped process, with time constants of 2 and 6 min but no time delay. Engineer B insists that the best fit is a FOPTDmodel, with ?=7 min and θ=1 min. Both engineers claim aproportional controller can be set at a large value for K꜀ to control the process and that stability is no problem. Basedon their models, who is right, who is wrong, and why? Use a frequency-response argument.
