基于MEMS技术的三角翼飞行器涡流控制系统研究

Research on Delta Wing Vehicle Vortices Control System Based on MEMS Technique

飞行器涡流控制是运用流体喷、吸,可主动配置的控制面,前缘、后缘襟翼,可变形可跳动边缘及MEMS微动作器等来对涡流高感受区施加扰动改变或破坏其对称性,从而获得飞行器所需要的滚转、俯仰、甚至偏航空气动力的控制技术。针对一种采用了MEMS作动器的三角翼模型作为涡流控制系统的简化模型,提出了涡流控制系统的设计构想,并利用对现有数据对飞行器滚转力矩特性进行了仿真,结果表明当力矩特性具有良好的线性时,使用PID控制系统能得到比较好的响应曲线。

Vehicle vortices control is a kind of control technique which uses fluid jet and suction, active configuration of control surface, leading--edge and trailing-- flap, edge varied with transfiguration and flop, MEMS micro actuators etc. to add disturbance on vortex to alert or break it＇s symmetry to generate a rolling moment, pitching and yawing moments. In allusion to a kind of delta wing model which uses MEMS actuators as vortices control system simplified model, a vortices control system conception is presented and then a simulation is carried out using the data available. Results show that using PID control system can achieve good response curve when movements characteristic is excellent linearity.
