A process with open-loop model G(s) =Ke

Home » Control Systems » Control systems miscellaneous » Question

A process with open-loop model
G(s) = Ke^–sT4
τs + 1

is controlled by a PID controller. For this process—

1. the integral mode improves transient performance.
2. the integral mode improves steady-state performance
3. the derivative mode improves transient performance
4. the derivative mode improves steady-state performance.
5. B and C both

Correct Option: E

(B, C) As we have discussed in the synopsis that derivative mode improves transient response while integral mode improves the steady-state performance.
Hence alternative (B) and (C) both are the correct choice.

G(s) =	Ke^–sT4
	τs + 1
