Abstract: An apparatus, system, and method are disclosed for preventing turbocharger overspeed in a combustion engine. The method includes determining a turbocharger error term as a difference between a nominal turbocharger maximum speed and a current turbocharger speed. The method further includes determining a turbocharger speed derivative with respect to time. The method includes calculating a turbocharger control response based on the turbocharger error term and the turbocharger speed derivative with respect to time. The turbocharger control response may be a modified turbocharger maximum speed calculated by determining a reference speed multiplier based on the turbocharger error term and the turbocharger speed derivative with respect to time, and multiplying the reference speed multiplier by the nominal turbocharger maximum speed. The method thereby smoothly anticipates turbocharger transient events, and prevents an overspeed condition of the turbocharger.

Abstract: A roll product is wrapped with a sheet of stretch wrap packaging material dispensed from a stretch wrap dispenser. A portion of the sheet is positioned between a clamp and the stretch wrap dispenser so that the portion of the sheet is across a load path between the load and a roller for rotating the load. The load is transported along the load path and placed in driving contact with the roller. The load is rotated by driving the load with a roller. The clamp is moved from a first location to a second location where the sheet is wrapped around the load and secured in place by another portion of the sheet.
