A new SSI algorithm for LPTV systems: Application to a hinged-bladed helicopter
Many structures can be modeled as linear time-invariant systems. Subspace methods are able to identify linear time-invariant systems. Rotating systems are periodically time-varying systems. A new periodic identification algorithm deals with rotating systems. The periodic algorithm is tested on helicopter simulated data.
