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 (220) comprises a first plurality of feedback loops (270) to receive a plurality of commands representative of a desired piston (252) position and to generate, from the plurality of commands, a plurality of position difference signals (315) which represent a difference between a desired piston (252) position and a current piston (252) position, a plurality of amplifiers (206, 210) to generate, from the plurality of position difference signals (315), a corresponding plurality of magnetic flux target signals (320), a second plurality of feedback loops (272) to receive, from the plurality of amplifiers (206, 210), the plurality of magnetic flux target signals (320), wherein the magnetic flux target signals (320) represent a desired magnetic flux measurement in the servo valve (220), and to generate, from the plurality of magnetic flux target signals (320), a plurality of magnetic flux difference signals (325) which represent a difference between a desired magnetic flux measurement and a current magnetic flux measurement, and an assembly to regulate the servo valve (220) using the plurality of magnetic flux target signals (320). Other embodiments may be described.
