The experiments have demonstrated a high robustness of the method to in-environment disturbances, such as wind, and its easy deployability. Zhang, J., Jia, L., Niu, S., et al.: A space-time network-based modeling framework for dynamic unmanned aerial vehicle routing in traffic incident monitoring applications. The circulant digraph includes more vertices than the number of unmanned aerial vehicles and. Each UAV then executes a flight path corresponding to a directed cycle of the circulant digraph where each vertex of the circulant digraph corresponds to two waypoints.

In addition to the theoretical background of the method, an experimental verification in real-world outdoor conditions is provided. Collisionless flight is achieved by overlaying a circulant digraph with certain characteristics over a model of the area to be flown. The approach is characterized by low computational complexity and does not require any UAV dynamics model (just periodical measurements from basic onboard sensors) to obtain proper tuning of a controller. The proposed method relies on an optimization procedure using Fibonacci-search technique fitted into bootstrap sequences, enabling one to obtain a global minimizer for a unimodal cost function. For example, the sum of absolute values of the tracking error samples or performance indices, including weighed functions of control signal samples, can be penalized to achieve very precise position control, if required. Required controller properties may be simply interpreted by a cost function, which is involved in the optimization process. The controller tuning is performed fully autonomously during flight on the basis of predefined ranges of controller parameters. A second craft that exhibits detachable limbs for greatly enhanced transportation efficiency is also in development.The paper presents a novel autotuning approach for finding locally-best parameters of controllers on board of unmanned aerial vehicles (UAVs). A custom high-level controller for the craft was written with the intention that troops should be able to send commands to the platform without having a dedicated pilot. Preliminary tests show successful operation of the craft, although more development is required before it is deployed in field. This controller was then implemented in hardware and paired with the necessary subsystems to complete the ANGEL platform. A complete simulation model of the ANGEL system dynamics was developed and used to tune a custom controller in MATLAB and Simulink®. The ANGEL system was designed specifically for use in a combat theater where robustness and ease of control are paramount.

These other projects use pre-fabricated quadrotor platforms and a series of external sensors in a mock environment that is unfeasible for real world use. Many current research endeavors into the field of quadrotors for use as unmanned vehicles do not utilize the broad systems approach to design and implementation.
