摘要：This research proposes a direct sensorless MaximumPower Point Tracking (MPPT) Tip Speed Ratio (TSR)control based on wind speed and rotor speed estimationfor Wind Generation System (WGS) with direct driven PermanentMagnetic Synchronous Generators (PMSG). Also inthis paper, a new improved technique to estimate the rotorspeed using back-EMF is introduced. The new technique isdesigned based on the mathematical residual theorem. Thecontroller uses an estimated wind speed data derived fromelectrical measurements of voltage and current along with thepreviously estimated PMSG rotational speed. Using rotationaland wind speeds estimated data, the TSR is obtained usingcalculation method and set side to side to its optimal value.The proposed controller uses only the stator currents andvoltages measurements to control the WGS. The validationof the proposed controller is shown by MATLAB/SIMULINKsimulation.
