摘要： To ameliorate the detrimental effects of time delays, techniques and systems are disclosed for detecting time delays in a plant, facility, or environment (such as a power system) controlled by an NCS, and for providing more resilient control capabilities for adapting to the detected time delays. A time delay estimate can be determined by comparing the expected state of the plant, calculated from a plant model, with the state of the plant described by its telemetry data. Techniques for adapting to a time delay include: switching to an emergency controller and acting in accordance with a local reference model; sending adjusted control commands in accordance with an expected plant state; and instructing a transmitter to transmit subsequent communications packets over multiple redundant communication channels.

摘要： Computational models and methods and systems of using the model to estimate variable time delay in the sensorimotor system of a subject are provided. The computational model can estimate variable time delays in the sensorimotor system, predict sensory states based on delayed sensory feedback, and/or control the system in real time. The subject can be a human or a primate. Simulation experiments can show how the model can explain a sensorimotor system's ability to compensate for delays during online learning and control.
