Moving mass control (MMC) is a flight control technique that provides several unique advantages over conventional aerodynamic control surfaces, particularly for near space vehicles. In this study, we propose an MMC strategy for roll control of low-speed flexible HALE aircraft. Two internal moving masses are used to produce rolling moment rather than conventional ailerons. The complete equations of motion of the flexible aircraft carrying moving mass are first derived in terms of quasi-coordinates. A simplified model integrated with unsteady aerodynamic loads is obtained for roll control. The effect of moving mass positions on rigid-body motion and aeroelasticity couplings are analyzed. The feasibility of the mass-actuation concept for roll control of the flexible aircraft is primarily proven. The roll control ability and aeroelastic characteristics can be improved through the reasonable design of the moving mass system. The dynamic behavior of the system, while the mass travels along the wing, is simulated, implying that the elastic motion induces the delay effect in the roll motion of the flexible model compared with the rigid model. A roll rate control system is designed and analyzed to demonstrate the feasibility of using moving masses in real-time flight control.

运动质量控制（MMC）是一种飞行控制技术，与传统的空气动力学控制表面相比，具有许多独特的优势，尤其是对于近太空飞行器而言。在这项研究中，我们提出了一种MMC策略，用于低速柔性HALE飞机的侧倾控制。两个内部运动质量用于产生侧倾力矩，而不是传统的副翼。首先根据准坐标导出携带飞行质量的柔性飞机的完整运动方程。获得了一个简化模型，该模型集成了不稳定的空气动力学负载，用于侧倾控制。分析了移动质量位置对刚体运动和气动弹性耦合的影响。质量致动概念用于柔性飞机的侧倾控制的可行性已得到初步证明。通过合理设计运动质量系统，可以改善侧倾控制能力和气动弹性特性。模拟了质量沿机翼移动时系统的动态行为，这表明与刚性模型相比，弹性运动在柔性模型的侧倾运动中引起延迟效应。设计并分析了侧倾率控制系统，以演示在实时飞行控制中使用移动质量的可行性。
