  abstract = {The present study was carried out in order to track the maximum power point in a variable speed turbine by
minimizing electromechanical torque changes using sliding mode control strategy. In this strategy, first, the rotor speed is set
at an optimal point for different wind speeds, as a results of which, the tip speed ratio reaches an optimal point, mechanical
power coefficient maximizes, and wind turbine produces its maximum power and mechanical torque. Then, the maximum
mechanical torque is tracked using electromechanical torque. In this technique, tracking error integral of maximum mechanical
torque, error, and derivative of error are used as state variables. During changes in wind speed, sliding mode control is
designed to absorb the maximum energy from the wind and minimize the response time of maximum power point tracking
(MPPT). In this method, the actual control input signal is formed from a second order integral operation of the original
sliding mode control input signal. The result of the second order integral in this model includes, control signal integrity, full
chattering attenuation, and prevention from large fluctuations in the power generator output. Simulation results, calculated
using MATLAB software, have shown the effectiveness of the proposed control strategy for wind energy systems based on the
PMSG.},
