Constant-Power Load (CPL) introduces destabilizing effect to dc-dc converters, which may lead to voltage oscillation or collapse. To mitigate the destabilizing problem brought by CPL, a nonlinear boundary controller is proposed in this paper, which has a nonlinear switching line. The converters' dynamics on the state space plane is analyzed through phase portrait. The proposed controller is verified...
Topological structure is considered more and more important in managing a supply network or predicting its development. In this paper, a new framework is proposed to model the topological structure of supply networks, where different types of supply networks can be created just by introducing different supplier-customer connecting rules. Generally, the networks created in the framework are much different...
This paper describes a system design approach for wireless sensor network based wildfire monitoring, including the system architecture, hardware and software framework. Effectiveness of the solution is evaluated in terms of reactivity, reliability, robustness and network lifetime. The main contribution of the paper is the design of a sensor network that can meets the goal of reactivity and reliability,...
