Direct discrete-time flux-linkage control of bearingless synchronous reluctance motors

Direct discrete-time design is applied to flux-linkage control of a bearingless synchronous reluctance motor (BSyRM). Continuous-time state-space model of the BSyRM is first converted to its discrete-time counterpart. For the discretized system, a discrete-time full-state feedback controller is designed using the pole-placement method and internal model control approach. Operation of the controller is simulated and robustness against parameter errors is analyzed. Practical realization of the controller with a BSyRM prototype is also discussed.
