Regulation circuit for physical parameter - has linearisation block inserted in feedback path between non-linear regulation path and regulator providing setting value for latter

摘要

The regulation circuit has the actual value of a physical parameter supplied as a voltage signal (W) fed to one input of a regulator (R), providing a setting value (Y) at its output, fed to a non-linear regulation path (S), providing a regulation value (X) fed back to the regulator. The feedback path contains a linearisation block (LIN1) between the non-linear regulation path and the feedback input of the regulator, with a second linearisation block (LIN2) in the path of the voltage signal fed to the parameter input of the regulator.
