Abstract: An engine control system includes an engine controller configured to execute an open-loop model of the engine control system. The open-loop model receives a measured effector and boundary condition parameter vector and generates a synthesized engine operating parameter based on the measured effector and boundary condition parameter vector. The engine controller calculates a corrector error value between the synthesized engine operating parameter and a measured engine operating parameter, and determines an open loop corrector error calculated as a difference between the corrector error and a vector-matrix product of corrector state vector and a gain map/function. The engine controller applies the gain map/function to the open loop corrector error to determine an effector and boundary condition error vector of the measured effector and boundary condition parameter vector.

Abstract: Apparatuses, systems, and methods for placing one or more wires into split loom tubing. An apparatus is provided that includes a partial enclosure, a longitudinal channel, and a flared wedge. The partial enclosure has a proximal end and a distal end. The longitudinal channel runs from the proximal end to the distal end, and the channel has a width sufficient to guide a wire as it is placed into the split loom tubing. The flared wedge is coupled to the proximal end and has a width sufficient to stretch open an interior of the split loom tubing to facilitate transferring the wire from the channel into the split loom tubing. In operation, the split loom tubing is loaded with wiring by inserting the apparatus into the interior of the split loom tubing and by moving the apparatus along the length of the split loom tubing. This movement quickly and effectively deposits the wiring into the split loom tubing.
