This paper suggests a novel dynamic protection/control scheme with unified power flow controller (UPFC) to prevent transmission system overload. A transient energy function (TEF)-based model predictive control (MPC) methodology is developed to reduce control cost and enhance power grid resilience. First, a TEF and an associated cost function of UPFCs are constructed based on ac dynamic model with...
Timely detection and localization of the gas leak are heated issues in the area of wireless sensor networks (WSN). Different methods have been proposed for various applications. In this paper, a new scheme is presented to monitor and estimate the leak of gas source. In our proposed approach, the gas source is located by employing maximum likelihood (ML) while the gas concentration is collected by...
Production quality in the food production supply chain is studied in this paper. The deficiency of quality monitoring existing in traceability systems is analyzed. An abnormality diagnosis algorithm, pre-warning method and pre-warning system are presented. The potential production abnormality of the logistics unit in the whole supply chain is diagnosed; a warning is generated; and decision support...
To solve the high cost of design and the high failure rate of common digital compass used triaxial magnetic sensor, this paper designed a digital compass which is composed of two-axis magnetic intensity sensor and two-axis accelerated sensor. It uses the direction cosine transformation matrix between the geographic coordinate system and the carrier coordinates of the Earthpsilas magnetic field and...
Based on the actual project, establish the mathematical model of swingable arm and researches the laneway profiling control and track planning. Realizes automatic profiling control by using human simulating intelligent control (HSIC). The experimental result shows that this is a feasible solution.
