Multi-UAV cooperative target tracking with bounded noise for connectivity preservation

Rui Zhou, Yu Feng, Bin Di, Jiang Zhao, Yan Hu,jzhao@buaa.edu.cn

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 10,   Pages 1413-1534 doi: 10.1631/FITEE.1900617

Abstract: We investigate cooperative target tracking of multiple unmanned aerial vehicles (UAVs) with a limited communication range. This is an integration of UAV motion control, target state estimation, and network topology control. We first present the communication topology and basic notations for , and introduce the distributed . Then, convergence and boundedness of the estimation errors using the filter are analyzed, and potential functions are proposed for communication link maintenance and collision avoidance. By taking stable target tracking into account, a distributed potential function based UAV motion controller is discussed. Since only the estimation of the target state rather than the state itself is available for UAV motion control and UAV motion can also affect the accuracy of state estimation, it is clear that the UAV motion control and target state estimation are coupled. Finally, the stability and convergence properties of the coupled system under are analyzed in detail and demonstrated by simulations.

Optimal Scheduling of Variable-pressure Variable-flow Operation of Inverter-drive Pumps Connected in Parallel

Li Hongbin,Zhang Chenghui,Song Jun

Strategic Study of CAE 2001, Volume 3, Issue 9,   Pages 52-57

Abstract:

The paper analyzes common methods for the optimal scheduling modeling problem of variable-pressure variable-flow operation of inverter-drive pumps connected in parallel and compares the merits and defects of them. In the common method, the objective function is the shaft horsepower of the pumps and the constrained conditions are water supply target and high-efficiency area of pumps. In another method, the objective function is the square of the difference between the actual and needed flow when satisfying the lift target and the constrained conditions are high-efficiency areas of pumps. The paper proposes a new modeling method, which is compatible with the actual operation and has higher precision and satisfies the engineering requirement on lower switching frequency. Simulation results have proved its validity.
