Interface between processing environment optimization layers

Systems and methods are provided for interfacing multiple layers of optimization for a model of one or more processes in a processing environment to achieve increased or maximized stability in the underlying layer. To improve consistency between the solutions at the different model levels, the lower level of optimization can have extra constraints added to the optimization problem which target variables at their unconstrained values in the upper layer of optimization. The systems and methods can facilitate selection of variables to receive an external target such that stability of the solution is improved or maximized. This can be achieved, at least in part, by identifying variables that provide a reduced or minimized condition number for a sub-matrix in the lower level model when an additional external constraint is applied. The sub-matrix with the reduced or minimized condition number can correspond to a partitioned portion of the gain matrix that corresponds to unconstrained independent variables and constrained dependent variables.

A control system estimates a numerical value range within which a command value can fall from a distribution of second data relating to the command value in a learning data set used to construct a prediction model, and in such a manner that a first acceptable range prescribed by a preset first threshold value with respect to a command value for a subject device is extended, decides a second threshold value with respect to the command value for the subject device on the basis of the estimated numerical value range. Further, in an operational phase, on the basis of an output value from the prediction model, the control system decides a command value for the subject device within a second acceptable range prescribed by the decided second threshold value, and controls an operation of the subject device on the basis of the decided command value.

A dense array of sensors positioned in a virtual environment is reduced to a sparse array of sensors in a physical environment, which provides sufficient information to a controller that responds to environmental conditions and parameters in the physical environment in substantially the same manner as it would to the same environmental conditions and parameters in the equivalent virtual environment. Data from a sparse array of virtual sensors is correlated with data from a dense array of virtual sensors and is used for generating control signals for hardware devices that influence a real or virtual interior environment. The correlated data and the control signals are used to train an artificial intelligence based controller that then controls the values of the parameters of the interior environment. A model of the interior environment is created using basic parameters in a computer-aided design application.

This disclosure describes techniques for identifying and mitigating a voltage loss in a power transmission to a Remote Radio Unit (RRU) associated with Radio Frequency (RF) antennas of a telecommunications network. More particularly, a Supplemental Voltage (SV) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a primary Direct Current (DC) power source to the RRU and selectively cause a supplemental DC power source to transmit a supplemental voltage to the RF antennas. The SV controller may cause a supplemental DC power source to transmit a supplemental voltage to the RRU based on an empirical data analysis, sensory data analysis, or current environmental metadata. Further, the SV controller may determine whether the primary DC power source has suddenly ceased transmitting power to the RRU, and in doing so, cease transmission of a supplemental voltage to the RRU.
