Non-linear control system for a single input single output process

摘要

A control system and method for providing a nonlinear response for a single input-single output system. A system output is measured and compared against a predetermined set point. An error signal from this measurement is used to identify an entry in a lookup table. The entry is a control signal used to vary the input to the system so as to reach a desired output. The lookup table entries are configured so that as the output reaches the desired set point, smaller and smaller incremental steps are taken in varying the input.
