A current-state transformation turns the faulty PMSM model into an exact linear time-varying system, so an observer or GPEBO can directly estimate the inter-turn short-circuit fault severity.

Interturn Fault Detection in IPMSMs: Two Adaptive Observer-based Solutions
A current-state transformation turns the faulty PMSM model into an exact linear time-varying system, so an observer or GPEBO can directly estimate the inter-turn short-circuit fault severity.
