International Conference on Emerging Technologies and Factory Automation (ETFA)

作者： Marius Kloetzer Cristian Mahulea José-Manuel Colom Department of Automatic Control and Applied Informatics Gheorghe Asachi Technical University Romania Department of Computer Science and Systems Engineering University of Zaragoza Spain

This paper provides a strategy for supervising the motion of some mobile robots that evolve in the same environment. Some regions of the environment are assumed to have a limited capacity in terms of the number of robots that can simultaneously occupy them, and a set of possible trajectories is available for each robot. The solution comprises the construction of a specific Petri net model for the available trajectories, and the use of resource-allocation techniques based on restricted-capacity regions and on deadlock-free execution.

Test-driven programming

AIP Conference Proceedings 2013年第1期1570卷 455-460页

In this paper, are presented some possibilities concerning the implementation of a test-driven development as a programming method. Here is offered a different point of view for creation of advanced programming techniques (build tests before programming source with all necessary software tools and modules respectively). Therefore, this nontraditional approach for easier programmer's work through building tests at first is preferable way of software development. This approach allows comparatively simple programming (applied with different object-oriented programming languages as for example JAVA, XML, PYTHON etc.). It is predictable way to develop software tools and to provide help about creating better software that is also easier to maintain. Test-driven programming is able to replace more complicated casual paradigms, used by many programmers.

The paper deals with one possible control method of a tubular chemical reactor. The procedure is based on the decomposition of the controller on a nonlinear static part and an adaptive linear dynamic part. Derivation of the nonlinear static part uses inversion and subsequent polynomial approximation of simulated or measured steady-state characteristics of the reactor. The nonlinear part of the closed-loop composed of the nonlinear static part of the controller and nonlinear model of the reactor is then approximated by an external linear model with parameters recursively estimated via a corresponding delta model. The control law is obtained using the linear quadratic control theory.

Heat exchange belongs to the class of basic thermal processes which occur in a range of industrial technologies, particularly in the energetic, chemical, polymer and rubber industry. The process of heat exchange is often implemented by through-flow heat exchangers. It is apparent that for an exact theoretical description of dynamics of heat exchange processes it is necessary to use partial differential equations. Heat exchange is namely a process with distributed parameters. It is also necessary to take into account its nonlinear and stochastic character. In spite of these facts, most of thermal equipment is controlled by digital modifications of PID controllers at present. This paper deals with identification of a dynamic behavior of a through-flow heat exchanger and a design of an self-tuning predictive controller for its control. The designed controller was verified by a real-time control of experimental laboratory heat exchanger.

Wireless Sensor Networks Clock Synchronization with Selective Convergence Rate

引用

IFAC Proceedings Volumes 2013年第10期46卷 146-151页

This paper focuses on the Wireless Sensor Network (WSN) synchronization problem for event-driven measurement applications. The objective is twofold: i) to provide high accuracy in the area where an event is detected, ii) to ensure a long network life time. These two objectives are conflicting. In fact, to increase the synchronization accuracy packets must be exchanged at higher rate, thus affecting the network lifetime. In several interesting applications a trade-off can be achieved based on the observation that, if the goal is to observe a localized event, only the portion of the network surrounding the detected event requires a higher accuracy. The proposed algorithm represents a formalization of this idea. Simulations are done to show the effectiveness of the proposed algorithm.

Self-tuning control of non-linear servomotor: Standard versus dual approach

引用

WSEAS Transactions on systems 2013年第6期12卷 304-313页

作者： Bobál, Vladimír Chalupa, Petr Dostál, Petr Kubalcík, Marek Centre of Polymer Systems University Institute Tomas Bata University in Zlín T. G. Masaryka 5555 760 01 Zlín Czech Republic Department of Process Control Faculty of Applied Informatics Tomas Bata University in Zlín T. G. Masaryka 5555 760 01 Zlín Czech Republic

The majority of processes met in the industrial practice have stochastic characteristics and eventually they embody non-linear behaviour. Traditional controllers with fixed parameters are often unsuitable for such processes because their parameters change. The changes of process parameters are caused by changes in the manufacturing process, in the nature of the input materials, fuel, machinery use (wear) etc. Fixed controllers cannot deal with this. One possible alternative for improving the quality of control for such processes is the use of adaptive control systems. Different approaches were proposed and utilized. One successful approach is represented by self-tuning controller (STC). This approach is also called system with indirect adaptation (with direct identification). The main idea of an STC is based on the combination of a recursive identification procedure and a selected controller synthesis. Presently, most of the STCs are based on the Certainty Equivalence (CE) Principle, which is only suboptimal. One of the possibilities to improve the quality of these adaptive control methods is usage of an Adaptive Dual control (the bicriterial approach). In this paper, the bicriterial approach is verified and compared with some other adaptive control approaches based on the CE Principle by the real-time control of a highly non-linear laboratory model, the DR300 Speed control with Variable Load.

Speed up of XML parsers with PHP language implementation

引用

AIP Conference Proceedings 2012年第1期1497卷 395-401页

作者： Bozhidar Georgiev Adriana Georgieva Fac. Computer Systems and Control Technical University of Sofia Sofia Bulgaria Fac. Applied Mathematics and Informatics Technical University of Sofia Sofia Bulgaria

In this paper, authors introduce PHP5's XML implementation and show how to read, parse, and write a short and uncomplicated XML file using Simple XML in a PHP environment. The possibilities for mutual work of PHP5 language and XML standard are described. The details of parsing process with Simple XML are also cleared. A practical project PHP-XML-MySQL presents the advantages of XML implementation in PHP modules. This approach allows comparatively simple search of XML hierarchical data by means of PHP software tools. The proposed project includes database, which can be extended with new data and new XML parsing functions.
