1. A process controlled in feedback mode has the transfer functions of the process, the transmitter sensor and the final element equal to, respectively:
Gp (S) = (6.37)/(5.0030S + 1) // Gst (S) = 24.0 // Grp (S) 0.0103
Calculate the steady-state error when the input variable in the process is subjected to a perturbation with a negative amplitude degree equal to 0.25. It is known that the proportional gain of the controller is equal to 1.9.
