A controller (100) for a wind turbine (1) comprises a power controller unit (101) for controlling a power output of an electric generator (10) comprised in the wind turbine (1). The power controller unit (101) operates the electric generator (10) according to a speed reference value (211, 213) and a power reference value (212, 214), the speed reference value (211, 213) and a power reference value (212, 214) being chosen along a linear operating trajectory (204, 205) in a power vs speed graph (200), the linear operating trajectory (205) including a point (210) corresponding to the nominal power (212) and the nominal generator speed (211). The power controller unit (101) includes a slider command (103) for selecting the angular position of the linear operating trajectory (204, 205) in the power vs speed graph (200). 一种用于风力涡轮机（1）的控制器（100）包括用于控制包括在风力涡轮机（1）中的发电机（10）的功率输出的功率控制器单元（101）。功率控制器单元（101）根据速度参考值（211、213）和功率参考值（212、214）来操作发电机（10），速度参考值（211、213）和功率参考值(212、214)沿着功率对速度图(200)中的线性操作轨迹(204、205)被选择，线性操作轨迹(205)包括对应
