Problem 5. The data given in the following table represent experimental, frequency response data for a process with the following transfer function: G(s) = 2e-os = TS+1
(a) Choose a reasonable data point to estimate time constant t and time delay 0 in the transfer function G(s). 2(1-5) (b) If this process is connected to another process with a transfer function of whose block diagram is shown below, what would be the output response y'(t) for a sinusoidal input a change of u'(t) = sin (t)? S = U'(s) 2(1 –s) Y'(s) G(S) S
