本文考虑了以前开发的一种用于变转速风力发电机2区控制的自适应控制方案。本文研究了转矩控制器的理论稳定性问题，证明了在恒风速输入情况下转矩控制律下转子转速是渐近稳定的，在时变风输入情况下是L/sub /稳定的。进一步推导了增益自适应律中/spl gamma//sub /spl Delta/M/的选择方法，以保证自适应增益M收敛到其最优值M*。
This article considers an adaptive control scheme previously developed for region 2 control of a variable speed wind turbine. In this paper, the question of theoretical stability of the torque controller is addressed, showing that the rotor speed is asymptotically stable under the torque control law in the constant wind speed input case and L/sub 2/ stable with respect to time-varying wind input. Further, a method is derived for selecting /spl gamma//sub /spl Delta/M/ in the gain adaptation law to guarantee convergence of the adaptive gain M to its optimal value M*.
