采用基于Kriging的遗传算法（GA）对等离子体激励器（PA）的工作参数进行优化。在这项研究中，升力最大化问题的圆柱周围被认为是。两个PA安装在圆柱体的上侧和下侧。这个问题类似于翼型设计，因为圆形具有作为翼型的潜力，这是由于通过具有四个设计参数的PA来控制流动循环。为了克服数值模拟耗时的缺点，通过风洞试验对气动性能进行了评估。开发的优化系统探索的最佳波形参数的交流电压通过改变波形自动。基于这些结果，获得了最优设计和全局设计信息，同时与全析因实验相比，大大减少了所需的实验次数。采用方差分析和散点图矩阵进行设计知识发现。根据发现的设计知识，发现两个PA的占空比是产生升力的重要参数。
Kriging-based genetic algorithm (GA) was employed to optimise the parameters of the operating conditions of plasma actuators (PAs). In this study, the lift maximisation problem around a circular cylinder was considered. Two PAs were installed on the upper and the lower side of the cylinder. This problem was similar to the airfoil design, because the circular has potential to work as airfoil due to the control of flow circulation by the PAs with four design parameters. The aerodynamic performance was assessed by wind tunnel testing to overcome the disadvantages of time-consuming numerical simulations. The developed optimisation system explores the optimum waveform of parameters for AC voltage by changing the waveform automatically. Based on these results, optimum designs and global design information were obtained while drastically reducing the number of experiments required compared to a full factorial experiment. An analysis of variance and a scatter plot matrix were introduced for design knowledge discovery. According to the discovered design knowledge, it was found that duty ratios for two PAs are an important parameter to create lift.
