Along with the further study of multi-terminal VSC-HVDC and HVDC Grid, as the key equipment, high voltage dc circuit breaker (DCCB) received great attention. Firstly, based on the comparison of the existing circuit breaker, a new topology for current-limiting HVDC circuit breaker was proposed in this paper. Secondly, the working principle of this breaker is analyzed. This topology allowing IGBT (insulation...
This paper presents an overview of recent trends in Battery System Management Architectures (BSMAs). After introducing the main characteristics of large battery packs, the state of the art in BSMAs is discussed. Two emerging concepts are in the focus of this contribution. On the one hand, there is a development from centralized battery management architectures with a single control entity towards...
We consider discrete-time distributed estimation on a directed graph with switching topologies. Motivated by a recent PI consensus filter, we modify the protocol and remove the constraint on bi-directional information exchange and gain conditions that require global topological information. The protocol is then extended to switching topologies. Convergence results for time-invariant inputs under both...
We consider the problem of source seeking using a group of mobile robots equipped with sensors for source concentration measurement. In the formulation, the robot team cooperatively estimates the gradient of the source field, moves to the source by tracing the gradient-ascending direction, and keeps a predefined formation in movement. We present two control algorithms with all-to-all and limited communications,...
This paper proposes a network-coding-based multicast routing protocol(NCMRP) at IP layer for wired networks. The basic idea of NCMRP is that the source broadcasts routing packets to find multiple paths from the source to each sink, and the multicast topology is constructed with the multiple paths. NCMRP brings network coding into multicast with a few minor changes to the protocol packet formats of...
We study average consensus for directed graphs with quantized communication. In the presence of quantization errors, average consensus cannot be accurately reached. We develop robust consensus algorithms to reduce the effect of quantization. Linear matrix inequalities are used as design tools. Numerical results demonstrate the effectiveness of this method.
