A process with one time constant of 1 minute, a dead time of 20 seconds, and a process gain of 1.1 is controlled by a PI controller with a gain of 1 and an integral time of 0.2 minutes per repeat. Initially, there is no error between set point and process variable. Describe what would happen if the process experienced a disturbance that caused the process variable to instantly rise by 10%. How would you adjust the controller gain and integral action to solve the control problem in question above?
