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_________________?

Question

Accepted Answer

(Q/P) e-TdS/(Q/R) (S + 1). The transfer function relates the output y(t) to the input x(t). Based on standard process control analysis for a step response, option C matches the expected form.
