In wind power generators, position information is often required for tracking maximum power point as well as implementing control strategies for the Permanent Magnet (PM) generator. For such a system, failure of position sensor could potentially lead to major fault or require the system to be shut down. This could cause significant economic losses and also require unscheduled maintenance. This paper...
It is well known that slotting harmonics exist in most of the electrical machines. These harmonics may supply valuable information for condition monitoring of bearings, windings or rotor bars. Utilization of these harmonics for rotor speed and position estimation is limited mainly due to long sampling periods required by spectral estimation techniques. In this study, a novel speed and position estimation...
