Which of the following is the transfer function (Gc) of an ideal parallel PID controller? GC=Kc(1+is1+Ds)GC=Kc(1+,s)1GC=KC(1+isis+1)(Ds+1)GC=KC+sKI+KDs Temperature Th2 is to be controlled by adjusting flow rate, wc. The temperature sensorit transmitter (TT) is direct acting. Figure E8.15 Should the control valve be fail-open or fail-closed and Should the controller be direct-acting or reverse-acting? Fail close and reverse acting Fail close and direct acting Fail open and reverse acting Fail open and direct acting Which of the following is TRUE in the effect of increasing controller gain on the process response for proportional controller The offiset decreases The offset remains unchanged. The response becomes less oscillatory. The response does not change at all. The following graph shows controller responses to a disturbance. Which controller is responsible for Response A
