WebApr 25, 2024 · One can obtain precise values of the setpoint so that accurate pressure and temperature values can be maintained. A few of the limitations of PID are: These … WebThe sign of Kp tells us the direction the PV moves relative to the CO change. The negative value found above means that as the CO goes up, the PV goes down. We see this “up-down” relationship in the plot. For a process where a CO increase causes the PV to move up, the Kp would be positive and this would be an “up-up” process.
