Extending Radial Basis Function Neural Networks to Azure Cloud Analytics for UAV Swarm Control

Radial Basis Function Neural Networks (RBFNNs) are particularly well-suited for modeling uncertain dynamics in UAV swarm formation control due to their localized activation functions and strong interpolation capabilities. Traditionally deployed on-device, RBFNNs offer fast approximation of nonlinearities but are constrained by limited computational resources, which restricts their scalability and responsiveness in dynamic environments. By integrating RBFNNs into Azure’s cloud infrastructure, we can significantly enhance their utility and operational impact across UAV swarms.

In decentralized UAV swarm systems, each drone typically runs a lightweight RBFNN to adapt its control signals based on local observations. However, this localized inference lacks global awareness and is vulnerable to noise, latency, and model drift. By shifting the RBFNN computation to Azure, UAVs can stream telemetry data to a centralized model that aggregates swarm-wide inputs, performs high-fidelity function approximation, and returns optimized control signals in real time. Azure’s GPU-accelerated environments allow for deeper RBFNN architectures and ensemble modeling, which are infeasible on embedded systems.

For example, in leader-follower scenarios where follower UAVs must track a dynamic leader, Azure-hosted RBFNNs can continuously learn and refine the leader’s trajectory model using historical and real-time data. This enables predictive control strategies that anticipate future states rather than react to current ones. Similarly, in constrained environments with unknown obstacles, cloud-based RBFNNs can integrate geospatial data, environmental maps, and swarm telemetry to generate adaptive control laws that are both collision-aware and formation-preserving.

Azure’s edge computing stack—particularly Azure IoT Edge and Azure Percept—can be used to deploy lightweight inference modules on UAVs that receive periodic updates from the cloud-hosted RBFNN. This hybrid architecture ensures low-latency responsiveness while maintaining the benefits of centralized learning. Moreover, Azure’s support for continuous integration and deployment (CI/CD) pipelines allows for real-time model updates, ensuring that the RBFNN evolves with mission demands and environmental changes.

Security and reliability are also enhanced in this cloud-augmented framework. Azure’s built-in compliance with aviation-grade standards and its support for encrypted data channels ensure that control signals and telemetry remain secure throughout the feedback loop. Additionally, Azure Monitor and Application Insights can be used to track model performance, detect anomalies, and trigger automated retraining when drift is detected.

In summary, migrating RBFNN-based UAV swarm control to Azure cloud analytics transforms a reactive, localized control strategy into a predictive, globally optimized system. This approach enhances formation stability, obstacle avoidance, and mission adaptability—while preserving the real-time responsiveness required for aerial operations.
