Stator Flux Finite-time Observer for Non-Salient Permanent Magnet Synchronous Motors

In this paper a gradient observer and finite-time observer of stator flux are developed for non-salient permanent magnet synchronous motors. The methods described here are based on implementation of linear time-invariant (LTI) filters and the dynamic regression extension and mixing (DREM) techniques. The motor resistance and inductance are assumed to be known.
