Client Requirements
The client required a heterogeneous unmanned system where a Unmanned Ground Vehicle (UGV) serves as a mobile base for an Unmanned Aerial Vehicle (UAV). Key requirements included providing charging support to significantly extend operational range, high adaptability in complex terrains, autonomous navigation with FPV remote control, and achieving high-precision autonomous landing on a dynamic platform with bidirectional energy and signal transmission.
Our Answer
We proposed an innovative air-ground coupling architecture that defines the UGV as the energy replenishment and mission extension center for the UAV.
-
Core Technology: Integrated an infrared-aligned landing system for dynamic recovery and implemented a nonlinear control strategy based on Lyapunov theory. By decoupling attitude and translational dynamics, we ensured self-stabilizing flight in complex environments.
-
Performance Optimization: Through Time-Varying Model Predictive Control (MPC) and fuzzy logic, task switching efficiency (e.g., hover-to-land) was improved by 40%, and energy consumption was reduced by 22%.
-
Reliable Communication: Employed a hybrid protocol with adaptive topology management, ensuring end-to-end latency below 0.25s and a packet loss rate within 5%.
