摘　　要：为了模拟带副翼二维机翼受闭环控制下的飞行状态。基于计算流体力学、采用动态嵌套网格技术求解非定常流动控制方程与动力学方程,结合PID闭环控制算法,对预设目标迎角的带副翼二维机翼舵面受控,做俯仰运动时的流场特性和舵偏角及机翼俯仰角度随时间变化历程进行了研究。结果表明,反馈控制响应迅速,能较快使机翼偏转到目标迎角,且俯仰震荡相对稳定之后与目标迎角之间误差较小。验证了闭环控制应用于虚拟飞行技术中的有效性,上述方法对于研究通用飞行器受控飞行中流动机理及动态特性具有较高的参考价值。Based on computational fluid dynamics,the dynamic nested mesh technique was used to solve the un-steady flow equations and dynamics equations and the PID(proportional integral-differential)closed-loop control al-gorithm.The characteristics of the flow field and the time variation of the tilting Angle and the tilting Angle of a two-dimensional wing with ailerons under the control of the rudder surface with predetermined target elevation were stud-ied.The results show that the response of feedback control is rapid,the wing can quickly deflect to the target elevation Angle,and the error between the pitch and the target elevation Angle is small after the pitch oscillation is relatively stable.The effectiveness of closed-loop control applied to virtual flight technology is verified.This method has a high reference value for studying the flow mechanism and dynamic characteristics of general-purpose aircraft in controlled flight.
