昆虫和仿生微型飞行器的扑动飞行不仅需要产生空气动力来支撑重量抵抗重力并向前行驶，还需要飞行控制以在飞行时保持平衡。在这项研究中，我们利用浸入边界格子玻尔兹曼方法对类蝴蝶扑翼翼体模型的飞行控制进行数值研究。首先，我们通过沿着身体移动重物来模拟俯仰运动的控制。发现通过P控制方案确定重物的位置可以控制俯仰角。其次，我们通过垂直于身体移动重物来模拟对滚动角的较大初始扰动的滚动运动的控制。研究发现，可以通过PI控制方案确定重物的位置来控制滚动角。最后，我们通过在机翼运动的顶部和/或下死点短暂中断机翼运动来模拟俯仰运动的控制。结果发现，俯仰角是通过PID控制方案确定中断间隔来控制的。此外，发现即使对于大扰动，本控制也能很好地工作。
Flapping flight of insects and bio-inspired micro air vehicles requires not only the generation of aerodynamic forces for supporting the weight against gravity and for driving forward, but also the flight control for maintaining the balance while flying. In this study, we investigate the flight control of a butterfly-like flapping wing–body model numerically by using the immersed boundary–lattice Boltzmann method. First, we simulate the control of a pitching motion by moving a weight along the body. It is found that the pitching angle can be controlled by determining the position of the weight with a P control scheme. Second, we simulate the control of a rolling motion from a large initial disturbance on the rolling angle by moving a weight perpendicular to the body. It is found that the rolling angle can be controlled by determining the position of the weight with a PI control scheme. Finally, we simulate the control of a pitching motion by interrupting the wing motion shortly at the top and/or the bottom dead centers of the wing motion. It is found that the pitching angle is controlled by determining the interval of the interruption with a PID control scheme. In addition, it is found that the present control works well even for a large disturbance.
