Abstract

A method and apparatus for controlling a valve/actuator plant (17) by generating a plurality of independent correcting control signals each (15) responsive to a plurality of respective input signals and at least one of these input signals being the set point signal (54). The plurality of independent correcting control signals includes a pneumatic flow signal. The correcting control signals may be derived from all linear control signals, all non-linear control signals, or a combination of linear control signals and non-linear control signals.
