The experimental response of the controlled variable y(t) for a step change of magnitude ‘P’ in the manipulated variable x(t) is shown below: The appropriate transfer function of the process is________?

A(Q/R) e-TdS/(Q/P) (S + 1)

B(Q/P) e-TdS/(Q/R) (S + 1)

C(Q/R) e-(P/Q)S/(TdS + 1)

D(Q/P) e-(Q/R)S/(TdS + 1)

Correct answer

B. (Q/P) e-TdS/(Q/R) (S + 1)

Explanation

The correct answer is (Q/P) e-TdS/(Q/R) (S + 1).
