Remaining useful life estimation for mechanical systems based on similarity of phase space trajectory

作者：

Highlights：

• RUL is estimated based on the similarity of phase space trajectory.

• Nonlinear degradation evolution is revealed by the phase space trajectory.

• Trajectory matching is not influenced by the scaling and shifting.

• The estimation accuracy is verified by simulated data and actual data.
