This paper studied the mathematical model and calculation of each component of small and medium-sized wind turbine generators to improve its stability and power generation efficiency. The optimal modal gain and maximum power tracking range are obtained based on the traditional torque curve method. A complete maximum power tracking control strategy is developed based on the optimal torque curve method to conduct in-depth study and improvement. Finally, the feasibility and superiority of maximum
