Mechanism and experiments of asymmetrical pitch system for MAV
In view of problem for miniaturizing Micro Air Vehicles (MAV), a novel asymmetrical pitch system faced to rotary wing MAV is introduced. The pitch mechanism and control characteristics are studied and analyzed. Because the deformation of elasticity link is key to generate the blade pitch, it is analyzed and calculated by elasticity finite element method. And the results illustrate the linear relationship between blade pitch angles and the output torque of the motor. Based on control system of asymmetrical pitch, mechanism experiments based on strain gauge are done, and the factors that affect the deformation of the elastic linkage is analyzed. Results indicate that mechanism of asymmetrical pitch is effective.
Control system for dynamic testing platform of asymmetrical pitch mechanism
为旋转翅膀的一个新奇不均匀的沥青系统被介绍。沥青控制特征被学习并且分析。因为有弹性的连接是在整个不均匀的沥青系统的关键部分，以便获得有弹性的连接变丑的变化，主要基于微天线车辆(MAV ) 和新控制的设备，系统在 TMS320LF2407 上装了的一个试验性的平台被设计。这个控制系统有它的压缩配置和可靠性。最后，使用这个系统为模仿飞控制 MAV 前面的、试验性的结果证明 MAV 的飞行态度能基于有弹性的连接的变化被控制。
