ABSTRACT:
A tuning adjustment for a PI controller is disclosed which produces a desired response for a controlled variable in a selective control loop having an external reset feedback signal for anti-reset-windup protection. The desired control effect is evident in the time response of the controlled variables return to set point when a select switches signals and suddenly selects an output limited PI controller to control a process variable, and the selected controller assumes control of the process variable starting with its output at the limiting value. The tuning adjustment is implemented by combining the signal selected for controlling the process variable and a tuning factor for use as the reset feedback signal for the PI controller.
