论文摘要
在本文中,我们处理了束缚翼系统的功率调节,并在减轻动态机械载荷和功率波动方面证明了可变式控制控制的优势。提出的方案是基于一种策略,该策略可在低速风中最大化能量捕获,并在高速风中防止过载。为了实现此策略,我们使用束带滚动速度控制器在低速风中跟踪最佳发电机速度,并在高速风中使用MIMO速度速度控制器来限制功率。控制器是使用H-含性方法合成的,并基于线性参数变化(LPV)系统,该系统表达系统的灵活动力学,这是系绳长度和力的函数。使用此方法,控制器在动态和参数不确定性方面具有鲁棒性,并且在高速风中,机翼的螺距角度最小化。我们进行大量模拟以证明控制器的性能。其中包括在具有逼真的湍流场的详细三维束缚翼系统模拟器中实现该方案。
In this paper, we deal with the power regulation of tethered-wing systems and demonstrate advantages of variable-pitch control in mitigating the dynamic mechanical loads and power fluctuations. The proposed scheme is based on a strategy that maximizes the energy capture during low-speed wind and prevents overloads during the high-speed wind. To realize this strategy, we use a tether reeling-speed controller to track the optimal generator speed during low-speed wind and a MIMO speed-force controller for power limitation during high-speed wind. The controllers are synthesized using H-infinity method and are based on a linear parameter varying (LPV) system that expresses the flexible dynamics of system as a function of the tether's length and force. Using this method, the controllers are made robust with respect to dynamic and parametric uncertainties and the wing's pitch angle activity is minimized during high-speed wind. We carry out extensive simulations to demonstrate the controllers' performance. These include the implementation of the scheme in a detailed 3-dimensional tethered-wing system simulator with a realistic turbulent wind field.
