The transfer function for an ideal proportional plus reset controller (reset time T) is_______________?
Correct answer: A. Kc[1 + (1/TS)]
- A. Kc[1 + (1/TS)]
- B. Kc(1 + TS)
- C. Kc/(1 + TS)
- D. Kc/[1 + (s/T)]
Explanation
A proportional plus reset controller combines proportional action with integral action, giving Gc(s)=Kc[1+1/(Ts)]. The 1/(Ts) term represents reset action and eliminates steady-state offset.
