In this paper, a class of tracking problem for multi-agent systems with both switching topology and time varying delays is investigated. Specially, we consider the agents' distribution, which agents are randomly deployed into the 2-dimensional space. With the assistance of Voronoi diagrams, this space is divided into many Voronoi cells. During the pursuit process, when a target enters a new Voronoi...
Spherical Unmanned Aerial Vehicle (UAV) is a typical nonlinear system. Its un-modeled dynamics, internal and external disturbance can both affect the flight control, which makes the design of the controller more complex. In order to improve dynamic performance, static performance and robustness of the control system, an Active Disturbance Rejection Control (ADRC) scheme of spherical UAV is presented...
Voronoi diagrams based localization scheme (VBLS) is a widely used algorithm among computational-geometry based localization algorithms. However, due to the fact that VBLS employs received signal strength indication (RSSI) as basis for measuring distance and the large errors of RSSI technique, the localization precision of VBLS is negatively affected. To solve this problem, an optimal region selection...
Wireless Sensor Networks (WSNs) have been broadly studied with advances in ubiquitous computing environment. Because sensor nodes are resource limited, it is important to use energy-efficient routing protocols. The cluster-based routing is an efficient way to decrease transmission traffic and distance, hence, reduce energy consumption. LEACH is a popular cluster-based protocol, which provides distributed...
In this paper, Linux-RTAI and Matlab/RTW is used to develop real-time control system for fast real-time simulation and implementation of the control algorithm. The hardware of the controller is based on PC/104 cards under Linux-RTAI operating system. The main characteristic of Matlab/RTW is that it can automatically generate the real-time simulation code for many target processors. The combination...
With the increasing development of computer network and multimedia technology, the virtual simulation for control system modeling is transforming from the centralized system into the distributed system gradually. According to the latest requirements of simulation, the paper introduces a kind of virtual simulation platform based on the web, which is built leveraging Flash technique and Java. With the...
