Figure 1a shows the response of a process to a setpoint (SP) increase of 5°C for two sets of controller tuning parameters. Figure 1b shows the response of the same process with the same two sets of controller tuning parameters in response to a disturbance. Curve A has Kc and τI values tuned for the performance objective of quarter amplitude decay ratio. Curve B is tuned for the performance objective of minimal overshoot. Answer the following questions based on Figure 1. Figure 1
