An adaptive feedback linearization strategy for variable speed wind energy conversion systems

An up to date review of continuously variable speed wind turbines with mechatronic variable transmissions

“…Although several points of CVSWTs with such mechatronic variable transmissions have been investigated in the above‐listed literature, other important characteristics, such as transmission efficiency and grid‐code compatibility, turbine blade, and system characteristics, should be thoroughly investigated and solidly justified because they are of utmost importance to CVSWTs with such mechatronic variable transmissions.…”

Comprehensive review of wind energy maximum power extraction algorithms

“…In [50] an adaptation law was chosen to provide an estimate of the turbine torque that varies with wind speed and a controller was then designed for the linearized system using linear control theory, with additional input that would result in a linear control law with the reference rotor speed. Reference [51] also proposes an adaptive feedback linearization to estimate the uncertain and changing plant parameters for a cage induction generator. The authors also develop a relationship between various parameters for ensuring the convergence of the system and hence the trade of between the desired dynamics and the size of the convergence region was taken into consideration in the design procedure.…”

Robust Gain Scheduled Control of a Hydrokinetic Turbine

“…While the method appears to work reasonably well, linearizing the plant in this way is quite difficult due to system uncertainty. In [90] an adaptive feedback linearization approach is employed to deal with these uncertainties, though the parameters that assign the tracking error (based on turbine speed) and torque estimator dynamics also affect the size of the region where convergence is guaranteed.…”
