1. A system comprising:
a plurality of structures each having a planar surface, the plurality of structures connected to form a structural array with a planar array surface;
a processing device configured to determine, based on one or more bias estimates and one or more structure constants, a correction for a structural displacement of the plurality of structures; and
an actuator configured to apply the correction to the plurality of structures by applying a physical displacement to the plurality of structures.
