14th international Scientific-Technical conference "Dynamic of Technical systems", DTS 2018

The designing of optimal energy-saving actuating elements for transport control systems with magnetic levitation (electromagnets with current windings and permanent magnets) is reduced to solving the following inverse problem. It is necessary to determine the dimensions and magnetomotive force of the actuating element, providing a given levitation force, magnetic induction in ferromagnets and a minimum mass of the actuating element. The solution of the direct problem (determination of the force of levitation and magnetic induction) is carried out by the finite element method. In the problem, the objective function is the mass of the actuating element and the restrictions are superimposed on the force and magnetic induction. Solving this optimization problem by the Lagrange method leads to inefficient algorithm. The article describes the proposed optimization method based on the transformation of constraints into objective functions, that is, the reduction of the problem to the multicriteria problem with consistent minimization of objective functions with a limited number of required parameters. A number of criteria are minimized analytically. The application of the complex criterion is considered. To reduce the time of solving the problem, the hierarchy of models is used: chain and field model. The proposed optimization method allows reducing the time of solving the problem by about two times. The cost of electricity due to the use of permanent magnets is reduced by four times. An example of optimization of the design of the actuating element of transport control system with magnetic levitation is considered. © The Authors, published by EDP Sciences, 2018.

For the airlines, safety is the foundation for their existence and development. Therefore, the management of risks is one of the most important parts of daily airline management. Uncertain factors such as weather changes, aircraft failures, and employee status all contribute to the occurrence of various types of aviation accidents. How to find, manage, and avoid risks through the improvement of management methods, the analysis of operational data and the application of various technical tools is the problems faced by most airlines. Taking Xiamen Airlines as an example, this article thoroughly studies the theory and methods of airline operations assessment and risk management based on the Analytic Hierarchy Process(AHP). Through the research on various elements involved in aviation operations, the comprehensive application of risk management, safety science theories and methods of complex systems and computer modeling, we have proposed the design and implementation of airline operational risk assessment model construction and monitoring systems based on AHP. Thus, timely warnings can be made and control measures can be taken during routine management to improve the company's safety management level and operational support capabilities.

The paper presents the approach to the car buffering problem in the paint shop from the perspective of modern industrial plant requirements. The control of buffering process is connected with sequencing problem. A sequence, in which car bodies are painted is particularly important, because the minimization of the number of painting guns changeovers results in minimizing production costs. The problem of car sequencing has been widely considered in the literature. However, a large number of assumptions and simplifications, made by the researchers, make it impossible to apply developed solutions in practice. The paper considers the car sequencing issue taking into account problems that occur on the production line in the real paint shop. After presenting the algorithm, used in the analyzed plant, four sequencing algorithms, used to define the output sequence from the buffer, are discussed. Two algorithms are modifications of the well known scheduling heuristics - that are SPT and LPT methods. Based on these rules and follow-up control idea two new algorithms are proposed. The input sequence is determined in one of two ways. The correctness of the car body buffer control in the paint shop was verified in the test carried out using innovative method - virtual commissioning. The aim of the research was to identify the most effective methods that will be developed in the future. During tests, the buffer flow was monitored in order to identify unfavorable buffering situations deemed unacceptable in real conditions. The most unfavorable cases are presented and discussed in the article.

Collaborative work is a complex activity that involves several actors thus managing it is complicated. This article addresses some matters of controlling collaborative work in the point of view of process management. The underlying objective is to discuss the issues from modeling to enacting collaborative processes in existing process management systems. To overcome the discussed problems, we are developing a process management framework that integrates directly the concept of collaborative task into both modeling language and enacting mechanism. Moreover, we propose a flexible approach that enables users to choose dynamically a suitable way to enact their collaborative tasks.

Canonical Correlation Analysis (CCA) is a data analysis technique used to extract correlated features between two sets of variables. An important limitation of CCA is that it is a linear technique that cannot capture nonlinear relations in complex situations. To address this limitation, Kernel CCA (KCCA) has been proposed which is capable of identifying the nonlinear relations with the use of kernel trick. However, it has been shown that KCCA tends to overfit to the training set without proper regularization. Besides, KCCA is an unsupervised technique which does not utilize class labels for feature extraction. In this paper, we propose the nonlinear version of the discriminative alternating regression (D-AR) method to address these problems. While in linear D-AR two neural networks each with a linear bottleneck hidden layer are combined using alternating regression approach, the modified version of the linear D-AR proposed in this study has a nonlinear activation function in the hidden layers of the alternating multilayer perceptrons (MLP). Experimental results on a classification and a multiple-output regression problem with sigmoid and hyperbolic tangent activation functions show that features found by nonlinear D-AR from training examples accomplish significantly higher accuracy on test set than that of KCCA.

This paper builds a model of predicting the rating of the University on the basis of a neural network in IBM SPSS Statistics. The choice is due to the fact that the program contains gradient descent error function, which is able to automatically configure the network for data classification. The authors describe the modeling technique, a step-by-step algorithm for selecting the architecture of the network, setting its parameters, training and testing. Experiment data of 1102 Russian universities and 123 indicators of their activity was used for this experiment. A vector was supplied as an input for the network, the coordinates of which were the average total score of each University. Indicators were considered independent variables. 30 out of 123 indicators were left for the study by the method of correlation analysis. The number of input neurons was equal to the number of independent variables. The output layer contained the amount of neurons equal to the number of dependent variables. The activation function of neurons in the hidden and output layer is sigmoid. The authors present the results of modeling. Using the constructed model, the input data was divided into clusters: "efficient", "inefficient". Centers of clusters were determined. The sample was split for two network architectures with different number of layers and neurons. The percentage of error on the control and training samples was calculated. Quality of the proposed model was evaluated using ROC (Receiver Operating Characteristic) curve. © 2018 CEUR-WS. All Rights Reserved.

This paper proposes the design of a rule-based controller developed from a fuzzy controller to be applied in a DC motor position control. The Rough Set Theory is a mathematical tool capable of generating a set of rules for a dynamic system. One of the main problems of fuzzy controllers is the computation time, higher than conventional controllers, due to complex operations such as fuzzification and defuzzification. In order to reduce the processing time, a rough controller composed of a set of rules and a simpler computational structure is defined. A PID controller is initially obtained with the Ziegler-Nichols method for gain adjustment, which is used in the design of a fuzzy controller with better performance and serves as a model in the design of rough controller. Computational simulations were performed in less time with the rough controller, which also guaranteed stable conditions and dynamic system characteristics.

11th IFAC conference on control Applications in Marine systems, Robotics, and Vehicles (CAMS)

作者： Hahn, Tobias Koschorrek, Philipp Jeinsch, Torsten Univ Rostock Richard Wagner Str 31-H-8 D-18119 Rostock Germany Voith Turbo GmbH & Co KG D-89522 Heidenheim Germany

By means of wave filtering a dynamic positioning system for ships can be developed which does not counteract high-frequency, wave induced oscillatory ship motion. For high-performance and energy-efficient operation, the wave filtering parameters must be adjusted according to the environmental conditions. This prevents unnecessary wear and tear of the propulsion system while still achieving a high level of control performance. If the characteristics of the wave disturbance vary during operation, an online update of the filter parameters is required in order to maintain the control performance. The filter parameter which is significantly influenced by the varied wave spectrum is the peak frequency of the wave-induced oscillatory ship motion. Hence, the online estimation of the peak frequency is the topic of this paper. The approach adopted is to determine the peak frequency based on the parameter identification of a low order auto regressive model. The practical problems that arise are addressed and modifications are proposed. The algorithms shown are tested and compared on the basis of real experiments on a model scaled ship with Voith-Schneider Propellers. The results show the improved reliability of the proposed detail solutions in terms of numerical robustness and capability for practical real-time application in continuous operation.
