Transfer of alignment and calibration of multiple sensors in flexible systems

A method for the transfer alignment and calibration of sensors in flexible systems is presented. Flexible systems are represented by high order differential equations and reduced in dimension by model order reduction techniques. Both disturbability of alignment errors by control and disturbance inputs are considered. The reduced order model is decomposed by non-symmetric Riccati decomposition into states that directly and indirectly affect alignment errors. A transfer alignment and calibration filter with control feedthrough is developed and demonstrated for the example of a large flexible aircraft model in turbulence.
