1) Consider cach of the following PID feedback control process responses to a disturbance. Briefly describe or list - what specific concern(s) is/are less than ideal about the control response - what tuning parameter(s) you would change - how you would change the tuning parameter(s) to improve the control response. a) (6 pts) 20 10 Process Variable 0 10 um 15 -10 -20 Time (mins) b) (6 pts) 35 30 25 20 Process Variable 15 10 5 0 0 10 20 50 -5 60 30 40 Time (mins) e) (6 pts) 100 80 60 Process Variable 40 20 0 -200 -40 -60 -80 10 15 Time (mins) d) Which tuning parameter is the biggest risk to use, and why?
