本文研究了原型“智能”转子的减载潜力。这是一种转子，其中叶片配备了许多控制装置，结合适当的传感器和控制器，可以局部改变叶片上的升力轮廓。使用专用系统识别技术的实验模型是由缩放旋转双叶片“智能”转子开发的，其中每个叶片都配备了后缘襟翼和应变传感器。设计了基于H∞环整形与固定结构前馈控制相结合的反馈控制器，使两个叶片扑动方向的根部弯矩最小。我们使用许多不同的实际负载场景来评估性能。我们表明，通过适当的控制技术，负载信号的方差最多可以减少 90%。
This paper studies the load reduction potential of a prototyped “smart” rotor. This is, a rotor where the blades are equipped with a number of control devices that locally change the lift profile on the blade, combined with appropriate sensors and controllers. Experimental models, using dedicated system identification techniques, are developed of a scaled rotating two-bladed “smart” rotor of which each blade is equipped with trailing-edge flaps and strain sensors. A feedback controller based on H∞-loop shaping combined with a fixed-structure feedforward control are designed that minimizes the root bending moment in the flapping direction of the two blades. We evaluated the performance using a number of different realistic load scenarios. We show that with appropriate control techniques the variance of the load signals can be reduced up to 90%.
