Patent number: 10185305Abstract: A control system for controlling actuators comprises a central processor, a plurality of actuators, and a plurality of servo systems for controlling the respective actuators. Each servo system is operable, independently of the central processor, to control a controlled parameter (Y) in accordance with a reference value (R). The servo systems and the central processor communicate via a non-deterministic communications system. The central processor and the servo systems provide, to the central processor via the non-deterministic communications system, offset signals representing offsets (R?Y) measured by the servo systems between reference R and actual Y values of the controlled parameter. The central processor compares the offsets (R?Y) measured by the respective servo systems one with another.Type: GrantFiled: October 17, 2013Date of Patent: January 22, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Secundino Vicente Vicente, Yngvar Rossow Sethne, Tuomo Eljas Kaikkonen
