Abstract
Systems to manage servo controls are disclosed. In some embodiments servo controls may implemented in systems to deflect control surfaces in aircraft. In one embodiment, a system to manage the output of a servo valve comprises a first plurality of feedback loops to receive a plurality of commands representative of a desired piston position and to generate, from the plurality of commands, a plurality of position difference signals which represent a difference between a desired piston position and a current piston position, a plurality of amplifiers to generate, from the plurality of position difference signals, a corresponding plurality of magnetic flux target signals, a second plurality of feedback loops to receive, from the plurality of amplifiers, the plurality of magnetic flux target signals, wherein the magnetic flux target signals represent a desired magnetic flux measurement in the servo valve, and to generate, from the plurality of magnetic flux target signals, a plurality of magnetic flux difference signals which represent a difference between a desired magnetic flux measurement and a current magnetic flux measurement, and an assembly to regulate the servo valve using the plurality of magnetic flux target signals. Other embodiments may be described.
