ABSTRACT:
A process controller controls an integrating-type process based on a measured process variable and a set point. The process controller includes an error generating circuit, a non-integrating control circuit and an adaptive bias circuit. The error generating circuit generates an error signal based on a difference between the set point and the measured process variable. The control circuit generates a control signal as a function of the error signal. The adaptive bias circuit adds a bias value to the control signal, the measured process variable or the set point. The bias value is selectively updated as a function of the error signal to force the error signal toward zero.
