ABSTRACT:
A controller for process control has an adaptive gain. The controller is used as part of a closed feedback loop, and will, in response to different variables, maintain a constant loop gain regardless of non-linearities in the system.
Signals representing the variables are transformed into corresponding active gain factors. The active gain of the controller is computed as a function of the product of the active gain factors and then translated to an output signal. One or more active gain factor is defined as having a first gain factor, at least one breakpoint, and a second gain factor. If two breakpoints are used, a base gain is interposed. Furthermore, one or more variables may have a step function as an active gain factor.
