Description of the project
Knowledge of the torque and torsional response of a maritime powertrain is important for emission-compliant control. Torque and torsional response are normally measured using strain gauges, dedicated torque sensors, or other instrumentation installed on the drivetrain. Torsional response can also be calculated if the external torsional forces acting on the powertrain are known, but measurements of this external forcing are rare in maritime powertrains. Instrumenting large maritime powertrains is also costly, and there is often not enough measured information available to fully determine the torsional response using conventional methods alone.
Unknown external forces and torsional response can instead be estimated using methods such as convex optimization or Kalman filtering. These torque estimation methods allow much more freedom in sensor placement and reduce the number of sensors needed to characterize the full torsional response of the powertrain.
