  • Patent number: 11392107
    Abstract: Machine elements can be displaced along disjoined path sections by position-controlled machine axes. Movement guidance of the machine elements from the end of a path section to the beginning of a directly following path section along a previously unknown path is provided, wherein location, velocity and acceleration are continuous along the previously unknown path and at the transitions between the path sections and the previously unknown path. Velocity, acceleration and jerk are limited. A preliminary axis guidance and a corresponding required axis time is determined for each of the axes. A greatest required axis time is determined therefrom which is then set as a final axis guidance for this axis. For other axes whose preliminary axis times are smaller than the greatest required axis time, the respective preliminary axis guidance is matched to the greatest required axis time, which is then adopted for the other axes as final axis guidance.

  • Patent number: 11387651
    Abstract: Systems and methods are described for coordinating volt-var control between sub-transmission and distribution systems. Distributed energy resources of a distribution system are aggregated into virtual power plants from which reactive power can optimally be dispatched to the sub-transmission system. A sub-transmission controller executes a volt-var AC optimal power flow optimisation function to minimize voltage fluctuations that might otherwise occur when coordinating with a distribution system having distributed energy resources. The distribution system can use a sensitivity matrix for regulating voltage at distribution feeders while fulfilling a transmission or sub-transmission system's demand requests.

  • Patent number: 11379637
    Abstract: Various embodiments relate to additive manufacturing in which the Langmuir equation can be used to predict composition in the processing. This equation can be integrated into a model with knowledge of elemental solubility and relative reactivity of relevant elements in the additive manufacturing processing. Use of thermodynamic principles can be programmed into a finite element modeling strategy integrating the Langmuir equation, coupling the thermal fields of additive manufacturing and the surrounding environments with the rules and/or equations to predict solute pickup and/or solute loss. The modeling strategy can be implemented to identify the elements in relative concentrations to be used in the additive manufacturing processing to provide for the controlled loss of certain elements to prevent absorption of unwanted elements into molten material, formed by additive manufacturing, from the atmosphere around the molten material. Additional systems and methods are disclosed.
