Question

A process with open-loop model $G\left(s\right)=\frac{K{e}^{-s{T}_D}}{\tau S+1}$ is controlled by a PID controller. for this process.

• A. the integral mode improves transient performance
• B. the integral mode improves steady-state performance
• C. the derivative mode improve transient performance
• D. the derivative mode improves steady-state perfomance

Answer 1

Answer: (B), (C)

the derivative mode improve transient performance

The integral mode improves steady state performance and the derivative mode improves the transient performance.
