On Sensorless Control of Synchronous Motor Drives

Development of generic framework for design and analysis of position and speed observers for synchronous motor drives.
A fundamental wave excitation technique for medium-high speeds region
- Immunity to stator resistance variation and inverter non-ideal compensation
- Speed error estimation in addition to and independent of position error estimation
Injectionless sensorless control of synchronous reluctance machine for zero to low speeds region
- Relies on switching actuations of Finite-Control-Set MPC
- Absence of LPF delivers high position observer bandwidth
