Stability analysis of FAST

hello everyone,

As I know:
      Linearization is useful for:

            *Full-system modal analysis (finding the frequencies, damping, and mode shapes of a stationary or operational turbine)

            *Linear-system-based controls design (linear state-space-based controls design)

            *Linear-system-based stability analysis

how i do the Linear-system-based stability analysis by the FAST.
Can you give me some advice?

Best regard

Dear Railiang,

By “linear-system-based stability analysis” I mean examination of the linearized state matrices and resulting eigenvalues/eigenvectors to identify modes that are negatively damped and to aid in identifying the source of the negative damping and potential remedies.

Best regards,

Dear Jason

  I heard that you have published the paper about the Linearzation theory and principles.I think it can help me well.

 Thank you for your reply.



Dear Ruiliang,

I’m sorry, but I’m not sure what paper you are referring to.

Best regards,
