20th international conference on methods and models in automation and robotics (MMAR)

Non-minimum phase objects cause problems in designing control systems due to unstable inverse dynamics. In the case of, considered in the paper, Van de Vusse nonlinear chemical reaction, non-minimum phase properties are in connection with the input multiplicity of the process. Control method proposed for this process relies on feedback linearization and linear quadratic control. Input-state linearization provides an exact linear model. Linear quadratic regulator uses obtained model and determines appropriate control law. this approach, providing that weights for the linear quadratic regulator are adjusted properly, delivers control system with good performance of output and state signals, despite the fact that the output of the process is not a state variable of the linear model. the solution also assures stability of the system.

In the paper, a variant of the genetic algorithm for finding the location and size of small holes is considered. Both linear and non-linear elliptic boundary value problems are introduced in two domains with the conditions of transmission on the common boundary. the expansion of the shape functional for non-linear part and the expansion of Steklov-Poincare operator for linear part are provided in order to determine the form of topological derivative for the coupled model. the value of topological derivative is used for computing the probability density applied later in generating location of holes for genetic algorithm.

In this paper a method of designing the rule bases of fuzzy controllers for Wheel Slide Protection Systems (WSP) for rail vehicles is presented. In this method results of simulation of two reference controllers are used, both of which use signals which are nor available during normal operation of the systems, i.e. adhesion coefficient and translation velocity of the vehicle. Simulations have performed on a simulation model of a braked rail vehicle and controllers implemented in Matlab Simulink (R). the proposed method makes possible automatization of the design process of WSP fuzzy controllers.

Spreading of misinformation on the web nowadays represents a serious issue, as their influence on peoples opinions may be significant. Fake news represents a specific type of misinformation. While its detection was mostly being performed manually in the past, automated methods using machine learning and related fields became more critical. On the other hand, deep learning methods became very popular and frequently used methods in the field of data analysis in recent years. the study presented in this paper deals with the detection of fake news from the textual data using deep learning techniques. Our main idea was to train different types of neural network models using both entire texts from the articles and to use just the title text. the models were trained and evaluated on the Fake News dataset obtained from the Kaggle competition.

the problem of selection of measurement data provided by sensor array so as to maximize the accuracy of parameter estimation of a distributed system defined in a given multidimensional domain is discussed. Usually, when designing an identification experiment for nonlinear models, the uncertainty of nominal parameters has to be taken into account. In particular, an iterative scheme for parameter estimation is proposed enhanced with sequential experimental design techniques where there is no particular information about the parameter distribution. the setting examined here correspond to situation where from among the observations provided by nodes of given sensor array the most informative measurements have to be selected in order to provide an update of the parameter estimates. Finally, a proposed approach is verified by a computer simulation regarding heat transfer problem.

In this paper a special case of non-integer filters namely hi-fractional filters (BFF) - are considered. those filters are characterised by three parameters and offer rich possibilities of frequency response shaping. this paper is a continuation of an earlier research and focuses on stable filters with eigenvalues in right complex half plane. Conditions on stability of such filters are presented, their impulse responses are analysed and certain remarks on frequency characteristics are given.

For more than a decade, the productivity of knowledge workers has been going down. In addition, the knowledge work content of products and services is increasing;this is creating a productivity crisis. Knowledge worker productivity can be increased by using better methods for defining, planning and controlling processes, not just production processes, but mainly Support processes where most knowledge workers are employed. the adoption of a process management culture is discussed, and highlighted in the context of two examples.

the need to reduce energy consumption, resources, the introduction of new and ecological materials, the multiplicity of modern technologies available, and the complexity and multi-branch nature of architectural and construction projects means that designers must make complex and difficult decisions. this work presents currently available and used in the AEC industry project tools, sustainable building design analysis and provides an overview of the possibilities of using artificial intelligence methods and tools, such as Knowledge Based Engineering (KBE), fuzzy logic, neural networks, genetic algorithms, Monte-Carlo simulation. these methods can be used in the early design stage to improve decision making process and to optimize both the design process and the project itself. this article presents possible ways of developing AI methods for wider application in architectural design with possibilities to commercialize them.

this paper addresses the design of an adaptive control strategy for an alcoholic fermentation bioprocess, which takes place inside of a Fed-batch Bioreactor (FBB). this bioprocess is highly nonlinear, some state variables are not measurable and moreover the reaction kinetics is not perfectly known. the kinetic parameters are estimated by using a high-gain nonlinear estimator. An asymptotic state observer is derived so as to provide the unavailable states necessary to the kinetics estimator. Finally, the indirect adaptive control law is designed by combining a linearizing controller with the nonlinear observers. Several numerical simulations are performed, in order to test the proposed nonlinear adaptive control strategy. © 2012 IEEE.
