When tuning or adjusting the PID controller coefficients Kp, K, and Ko, what term would you adjust and how (increase or decrease) to reduce or eliminate (a) rise time, (b) steady-state error, (c) settling time, and (d) percent overshoot? (e)What precaution or concern exists in adjusting the tuning parameters in systems where the feedback signal in noisy?

Explanation / Answer

In a PID controller, the proportional controller decreases steady state error and rise time; integral controller reduces rise time and eliminates steady state error; derivative controller decreases peak overshoot and settling time.

(a). Increase Kp and Ki

(b). Increase Kp and Ki

(c). Increase Kd

(d). Increase Kd
