Abstract

In controlled systems with dead time, particularly converter current controls, the reference value is fed directly to the final control element providing anticipatory control and, in addition is fed to the reference input of the controller through a dead time simulator. In accordance with a further feature, the difference between the input signal and the output signal of the dead time simulator can be added into the final control element as an additional control variable to compensate for inertia of the controlled system.
