The paper is devoted to the problem of a neural networkbased robust simultaneous actuator and sensor faults estimator design for the purpose of the Fault Diagnosis (FD) of non-linear systems. In particular, the methodology of designing a neural network-based H∞ fault estimator is developed. The main novelty of the approach is associated with possibly simultaneous sensor and actuator faults. For this purpose, a Linear Parameter Varying (LPV) description of a Recurrent Neural Network (RNN) is exploited. The proposed approach guaranties a predefined disturbance attenuation level and convergence of the estimator. The final part of the paper presents an illustrative example concerning the application of the proposed approach to the multi-tank system fault diagnosis. © Springer International Publishing AG 2017.

International Workshop on Robot Motion and control (RoMoCo)

The paper presents a robot control system design method based on hierarchical Finite State Machines (FSMs). The system is decomposed into subsystems. Each one of them is specified in terms of a hierarchical FSM. Previously the description of subsystem activities had been presented as a single, complex FSM, where with each of its states a behaviour was associated. Each behaviour was described by a flowchart. In this proposal behaviours are defined in terms of individual FSMs, resulting in a unified description using only the concept of an FSM. By using FSM specification tools that provide automatic code generation, the robot control system implementation is significantly accelerated. This approach has been verified through the design of a table-tennis ball collecting robot.

This paper presents a study devoted to recognizing horses by means of their iris and periocular features using deep convolutional neural networks (DCNNs). Identification of race horses is crucial for animal identity confirmation prior to racing. As this is usually done shortly before a race, fast and reliable methods that are friendly and inflict no harm upon animals are important. Iris recognition has been shown to work with horse irides, provided that algorithms deployed for such task are fine-tuned for horse irides and input data is of very high quality. In our work, we examine a possibility of utilizing deep convolutional neural networks for a fusion of both iris and periocular region features. With such methodology, ocular biometrics in horses could perform well without employing complicated algorithms that require a lot of fine-tuning and prior knowledge of the input image, while at the same time being rotation, translation, and to some extent also image quality invariant. We were able to achieve promising results, with EER=9.5% using two network architectures with score-level fusion. Copyright © 2018, The Authors. All rights reserved.

Chinese control Conference (CCC)

This paper develops new results on iterative learning control of a class of spatially interconnected systems for the particular case of the passive or active electric ladder circuits. This task is performed by converting the problem to one of stability along the trial for a differential linear repetitive process, leading to design based on linear matrix inequality computations. In particular, sufficient conditions for the existence of a control law are developed together with the design algorithms for the associated controller matrices. Under this control law the resulting ILC dynamics have an asymptotic convergence in terms of an error sequence formed from the difference between both the distributed reference trajectory and the current trial output produced. Finally, an illustrative simulation is given to demonstrate the feasibility and effectiveness of the new designs.

A method based on the elementary operations algorithm (EOA) is developed that reduces a system matrix describing a discrete linear repetitive process to a 2-D nonsingular Roesser form such that all the input-output properties, including the transfer-function matrix, are preserved. Some areas for possible future use/application of the developed results will also be briefly discussed. © 2017

Reservoir engineering is the term used in quantum control and information technologies to describe manipulating the environment within which an open quantum system operates. Reservoir engineering is essential in applications where storing quantum information is required. From the control theory perspective, a quantum system is capable of storing quantum information if it possesses a so-called decoherence free subsystem （DFS）. This paper explores pole placement techniques to facilitate synthesis of decoherence free subsystems via coherent quantum feedback control. We discuss limitations of the conventional ＇open loop＇ approach and propose a constructive feedback design methodology for decoherence free subsystem engineering. It captures a quite general dynamic coherent feedback structure which allows systems with decoherence free modes to be synthesized from components which do not have such modes.

Mobile wireless ad hoc network (MANET) becomes increasingly popular in responding to emergency situation. In this paper a possibility to support rescue team in monitoring heavy gas cloud with MANET comprised of mobile sensing devices is investigated. In the view of the current state of research, two methods for controlling mobile sensing devices during MANET self-organization are presented. The first one is based on a greedy approach whereas the second on a repulsion from the estimated centroid of a cloud and other nodes. Various variants of both methods are considered and their efficiency in terms of detection quality and energy saving is evaluated with MobASim simulation software. The results are discussed and one variant is chosen as the basis for the future research. © 2016 Polish Information Processing Society.

Determination of stresses in RC eccentrically compressed members using optimization methods

引用

AIP Conference Proceedings 2018年第1期1922卷

作者： Marek Lechman Andrzej Stachurski 1Building Research Institute 00-611 Warsaw Filtrowa 1 Poland 2Institute of Control and Computation Engineering Warsaw University of Technology 00-665 Warsaw Nowowiejska 15/19 Poland

The paper presents an optimization method for determining the strains and stresses in reinforced concrete (RC) members subjected to the eccentric compression. The governing equations for strains in the rectangular cross-sections are derived by integrating the equilibrium equations of cross-sections, taking account of the effect of concrete softening in plastic range and the mean compressive strength of concrete. The stress-strain relationship for concrete in compression for short term uniaxial loading is assumed according to Eurocode 2 for nonlinear analysis. For reinforcing steel linear-elastic model with hardening in plastic range is applied. The task consists in the solving the set of the derived equations s.t. box constraints. The resulting problem was solved by means of fmincon function implemented from the Matlab’s Optimization Toolbox. Numerical experiments have shown the existence of many points verifying the equations with a very good accuracy. Therefore, some operations from the global optimization were included: start of fmincon from many points and clusterization. The model is verified on the set of data encountered in the engineering practice.
