本文报道了风机控制领域最近才出现的一些新方法的调查研究结果。最近数年里,在时变不确定的紊乱风场中优化能量捕集效率和降低各个部件负荷的多元控制方法已经被广泛地研究。我们将相关的研究工作分为三类:风机建模和风机动力学研究、风机的主动控制和风机的被动控制。关于风机动力学研究,我们讨论了物理模型的建立,并且给出了空气弹性变形的分析工具。关于主动控制,我们审查了节距控制、扭矩控制和偏航控制等策略,包括相关的理论建立以及针对不同目的的应用情况。我们的研究主要关注风机叶片节距控制,节距控制被认为是在维持能量捕获性能的同时降低负荷的关键要素。关于被动控制,我们研究了调谐质量阻尼器、智能转子和Microtabs等技术。另外我们也提出了未来的一些研究方向。

Gable roofs with overhangs (eaves) are the common constructions of low-rise buildings on the southeastern coast of China, and they were vulnerable to typhoons from experience. The wind pressure distributions on gable roofs of low-rise buildings are investigated by a series of wind tunnel tests which consist of 99 test cases with various roof pitches, height-depth ratios and width-depth ratios. The block pressure coefficients and worst negative (block) pressure coefficients on different roof regions of low-rise buildings are proposed for the main structure and building envelope, respectively. The effects of roof pitch, height-depth ratio, and width-depth ratio on the pressure coefficients of each region are analyzed in detail. In addition, the pressure coefficients on the roofs for the main structure and building envelope are fitted according to roof pitch, height-depth ratio and width-depth ratio of the low-rise building. Meanwhile, the rationality of the fitting formulas is verified by comparing the fitting results with the codes of different countries. Lastly, the block pressure coefficients and worst negative pressure coefficients are recommended to guide the design of low-rise buildings in typhoon area and act as references for the future’s modification of wind load codes.
