EnglishPermanent-magnet synchronous motor (PMSM) drives are currently extensively used in many industrial applications, where continuity of operation and reliability are major features to be pursued. Indeed, a fault arising in an industrial process may produce not only safety problems but results in increased costs due to lost production. This chapter proposes the adoption of a robust nonlinear observer of the rotor angular position and velocity, which can be used for fault detection purposes. Convergence of such observer is ensured by the enforcement of a sliding motion on given surfaces, based on motor currents, which are of course affected by all faults influencing stator currents and can easily detect them. Simulations with additive faults have been reported, proving the reliability of the proposed solution. This edition first published 2013 © 2013 John Wiley & Sons, Ltd.

| Abstract: | Permanent-magnet synchronous motor (PMSM) drives are currently extensively used in many industrial applications, where continuity of operation and reliability are major features to be pursued. Indeed, a fault arising in an industrial process may produce not only safety problems but results in increased costs due to lost production. This chapter proposes the adoption of a robust nonlinear observer of the rotor angular position and velocity, which can be used for fault detection purposes. Convergence of such observer is ensured by the enforcement of a sliding motion on given surfaces, based on motor currents, which are of course affected by all faults influencing stator currents and can easily detect them. Simulations with additive faults have been reported, proving the reliability of the proposed solution. This edition first published 2013 © 2013 John Wiley & Sons, Ltd. |
