INTRODUCTION
The output of the process being controlled must evolve to follow the requested setpoint. This means that the appropriate command must be applied to the process power input at all times (or periodically in digital control). This control is calculated by a set of information processing operations, the corrector, which uses operators (summers, gains, integrators, derivators) to elaborate the control from the error signal and available auxiliary measurements.
