1:Consider the gas pressure problem shown below. The objective of this problem is to understand (via simulation) how the tuning parameters for a PI controller affect the stability and speed of response for setpoint changes or disturbances.

The relationship between the manipulated valve position (u in deviation variables) and the pressure in the second tank (y in deviation variables) is (with a time unit of minutes)

Assume that the dynamic behavior of the pressure measurement/transmitter is characterized by a first-order lag with ...
