Abstract
In Applied Research Project 12pu, DRDC Suffield is investigating the use of highly manoeuvrable small rotorcraft unmanned aerial vehicles (rUAVs) to provide situational awareness to dismounted soldiers. The rUAV must provide useful information that contributes to improved situational awareness. It must do so while minimizing operational workload and allow the rUAV operator to continue with their primary tasks. Thus, operation of the rUAV must not compromise operator safety but provide battle-space awareness that provides a force multiplier to the dismounted soldier unit. A Draganflyer X8 was selected to carry an autonomy package consisting of a light power-efficient computer, LIDAR, and cameras for the purpose of developing autonomous navigation, obstacle avoidance and landing behaviours. The autonomous performance of the rUAV must increase to meet the project objective. This report presents the reasons for developing a mathematical model of the Draganflyer X8. The resulting mathematical can be used for control systems design and analysis. The mathematical model is used to frame stability and performance criteria to mathematically formulate the real-world control problem governed by the underlying physics and performance specifications. This mathematical representation of the real-world problem will then be used to select control strategies best suited for the Draganflyer X8 in achieving project performance objectives. This paper presents a mathematical model of the Draganfly
