GATE 2018 Chemical Engineering: Match Process Dynamics (Dead-Time, Capacitive, Inverse Response, First-Order)

Chemical Engineering > GATE 2018 > Process Dynamics

Match the items in Column A with the items in Column B

Column A	Column B
(P) Pure dead-time	(I) φ = −90⁰
(Q) Pure capacitive	(II) $\frac{K}{1} − \frac{K}{2} with K 2 > τ K 1$
(R) Inverse response	(III) 0 < AR < 1
(S) First-order process with unit gain	(IV) AR = 1

Here, φ denotes the phase shift, K₁ and K₂ the process gains, τ the time constant, and AR the amplitude ratio.
