A novel asymmetrical pitch system for rotary wing is presented.The pitch control characteristics are studied and analyzed.Because elastic linkage is a key part in whole asymmetrical pitch system,in order to obtain the variation of the elastic linkage deformation,an experimental platform mainly based on the device of micro aerial vehicles(MAVs) and a new control system mounted on TMS320LF2407 are designed.This control system has its compacted configuration and reliability.Finally,using this system to control the MAV for simulating the flying forward,experimental results show the MAV's flight attitude can be controlled based on the variation of the elastic linkage.
Robotic unmanned blimps own an enormous potential for applications in low-speed and low-altitude exploration,surveillance,and monitoring,as well as telecommunication relay platforms. To make lighter-than-air platform a robotic blimp with significant levels of autonomy,the decoupled longitude and latitude dynamic model is developed,and the hardware and software of the flight con-trol system are designed and detailed. Flight control and navigation strategy and algorithms for way-point flight problem are discussed. A result of flight experiment is also presented,which validates that the flight control system is applicable and initial machine intelligence of robotic blimp is achieved.
