This paper addresses the experimental study on mapping multiple odor sources using the proposed algorithm based on Dempster-Shafer (D-S) theory in outdoor environments where the airflow almost always be strong and change with time both in direction and speed. In the proposed algorithm, by using the time series of the measurements from an anemometer and twelve gas sensors, the robot estimates the air-mass path to compute the belief mass function, and iteratively updates a grid map with D-S inference at each time step, mapping the distribution of two odor sources when the robot is cruising in the given search area. Here the air-mass path is defined as the historical trajectory most likely taken by the air mass contacting with the gas sensor mounted on the mobile robot, and an air mass might contain odor molecules, or just be a mass of clean air. In the grid map, each cell has two possible states, being occupied by an odor source, or not. In order to cut the calculation of the proposed algorithm, only the cells covered by the estimated air-mass path are updated. Experiments were carried out in outdoor nature environments, and the results illustrate that the proposed algorithm based on D-S theory can be applied to map multiple odor sources online.

A method for optimal sizing of hybrid system consisting of a Photovoltaic (PV) panel, diesel generator, Battery banks and load is considered in this paper. To this end a novel approach is proposed. More precisely a methodology for the design and simulation of the behavior of Hybrid system PV-Diesel-Battery banks to electrify an isolated rural site in southern Algeria Illizi (djanet). This methodology is based on the concept of the loss power supply probability (LPSP). Sizing and simulation are performed using MATLAB. The techno-economic study shows the performances of the proposed approach.

Unit-level modelling for KPI of batch hot strip mill process using dynamic partial least squares

引用

IFAC-PapersOnLine 2015年第28期48卷 1005-1010页

作者： Zhang, Kai Shardt, Yuri A. W. Chen, Zhiwen Ding, Steven X. Peng, Kaixiang Institute for Automatic Control and Complex Systems University of Duisburg-Essen Bismarckstrasse 81 BB Duisburg47057 Germany Key Laboratory for Advanced Control of Iron and Steel Process School of Automation and Electrical Engineering University of Science and Technology of Beijing Beijing100083 China

This paper proposes two different approaches to the problem of modelling the key performance indicators (KPIs) in a hot strip mill process (HSMP). The first approach takes into consideration the inherent dynamics of the process and develops a nonlinear iterative dynamic partial least squares (PLS) model. The second approach takes into consideration the multibatch property of HSMP to develop an appropriate multibatch modelling framework. Both approaches can be integrated into the dynamic model framework. The proposed framework is examined using industrial data obtained from a steel plant, where it provides a decent model for this process. However, there exists the potential for improvements including dealing with interbatch variability. © 2015, IF AC (International Federation of Automatic control) Hosting by Elsevier Ltd.
