Encoderless Vector Control of Pmsg for Wind Turbine Applications

The growing interest in wind turbine applications and the fast development of power electronics is making the manufacturers to find the most suitable and low cost technologies to put in practice. Permanent magnet synchronous generator are becoming more popular over the induction machine in wind turbine applications, because of the increased power to volume ratio, decreasing cost of magnets, and increased eficiency. In this scope, the purpose of this book is to find a solution in order not to use the sensor mounted on the shaft of the surface mounted permanent magnet machine for wind turbine applications.
