Bond graph method is a unified graphic method for modelling of engineering systems in several different energy domain. The open loop system of a Dynamically Tuned Gyroscope (DTG) is modelled using bond graph according to its structure. Using the bond graph method drift error caused by 2N angular vibration of the driving shaft is analysed, which shows the validity and intuitional effect of this method...
Contingency theorists have developed the basic grammar of coordination theory around the relationship between coordination mechanisms and circumstance like uncertainty, interdependence, work unit size and functional diversity. Recently, conceptual and empirical studies have emerged that offer new opportunities in coordination theory, for instance structure-process modeling. Meanwhile, model building...
In this paper we model the dynamics of a wave network consisting of three parallel edges and two loops by determining the number of the controllers and their locations. By frequency approach, we prove the asymptotic stability of the controlled system equipped with four controllers. We then deduce a simple form of the characteristic equation of the controlled system and prove that it is not exponentially...
The quantitative evaluation of system-of-systems architecture is a very important content in the research area of system-of-systems. The framework of system-of-systems analysis process and method of system-of-systems architecture description are reviewed. A new approach of system-of-systems architecture evaluation is proposed. The proposed evaluation approach is a bi-level approach. In the higher...
A wireless sensor network (WSN) is a wireless network consistsing of spatially distributed autonomous device using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants at different locations. A complete model of a sensor network is needed to improve upon its efficiency and design.Using a modeling and simulation...
Before fabricating the ordered product, an automated production system needs to evaluate its capacity in order to make the products in time and guarantee a deadlock-free manufacturing process. It is important to pre-evaluate the flexibility and agility of the automated production system and also simulate the system operation for the customized variety products in quick response and completely prevent...
Considering the MIMO networked control systems with sensors and controller interconnected by network, the sensors and controller are time-driven, and the actuators are on-chip actuators, the problems of modeling and stabilization of MIMO networked control systems with data packet dropout and time delay are studied. By two different methods, one is to introduce a memorizer in the front of the controller...
As System of Systems challenges become more pronounced, we are especially interested in a) the notion that each particular SoS problem is unique, possessing different sets of traits to differing degrees a) in the midst of this diversity, developing appropriate modeling for purposes of decision-making support. Because individual systems can operate independently within an system of systems, many traditional...
