Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 14:
15. A system, comprising:
a network of nodes each including a clock implemented in hardware;
a communication link connecting the nodes so as to share information between the nodes; and
one or more computers connected to the communication link and executing an algorithm that learns one or more skews of each of the clocks from the information, wherein:
the one or more skews are used to determine one or more corrective actions applied to one or more of the clocks so as to synchronize the clocks to a common clock rate,
the algorithm learns the skew and synchronizes the clocks using a closed loop hybrid state-feedback comprising:
communicating the information between a plurality of the nodes at one or more of the communication event times;
using the information to estimate the one or more skews of each of the clocks between the communication event times so that the estimates can be used to determine the corrective actions; and
at one or more of the communication event times, adjusting one or more clock rates of one or more of the clocks using the corrective actions so that the clocks are synchronized to the common clock rate.
