In this work, we establish different control design approaches for discrete-time systems, which build upon the notion of finite-step control Lyapunov functions (fs-CLFs). The design approaches are formulated as optimization problems and solved in a model predictive control (MPC) fashion. In particular, we establish contractive multi-step MPC with and without reoptimization and compare it to classic MPC. The idea behind these approaches is to use the fs-CLF as running cost. These new design approaches are particularly relevant in situations where information exchange between plant and controller cannot be ensured at all time instants. An example shows the different behavior of the proposed controller design approaches. Copyright © 2019, The Authors. All rights reserved.

This study is concentrated on investigating the different visual behaviors and HCI patterns between pilot flying and pilot monitoring while interacting with touchscreen controls on the flight deck. Twelve participants with flight experiences (M=1150, SD=4019.9) attended this research. The apparatus included Future Systems Simulator (FSS), eye tracker, and system usability scale (SUS). The designated scenario in the experiment was an instrument landing. All participants were required to perform two instrument landings in two different roles, pilot flying (PF) and pilot monitoring (PM). The order of role of randomized to eliminate practice effects. The results revealed that fixation counts of pilot flying were different among four AOIs, F (3, 9) = 10.58, p = .003, ηp2 = .78. On the other hand, the FC of pilot monitoring demonstrated a significant difference among four AOIs, F (3, 8) = 8.69, p = .007, ηp2 = .77. There was a significant difference between PF and PM on the subjective assessment of SUS total score, t (11) =3.85, p = 0.003, Cohen’s d= 1.11. The application of a touchscreen can integrate input and output in the same area for visual feedback. There is a rising need to simplify the future flight deck design based on the principle of human-centered design. Conclusion: The application of touchscreen flight controls may have the potential to facilitate single-pilot operations flight deck design in the future. TSCs considerations must be consistent with human information processing and pilots’ operational characteristics on the future flight deck. © 2023 The Aeronautical and Astronautical Society of the Republic of China.

Image quality parameters in application of compressed sensing for MRI data

AIP Conference Proceedings 2018年第1期1978卷

作者： Michał Staniszewski Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Informatics Akademicka 16 Gliwice Poland

The acceleration of Magnetic Resonance Imaging techniques is still very important in current development. The application of Compressed Sensing for medical data accelerates the acquisition time and satisfies the image quality. The method relies on the sparsity condition and requires only the most important data instead of acquiring all data according to the Nyquist-Shannon sampling theorem. The paper shows the application of different image quality parameters in order to compare the original method of Compressed Sensing for phantom and medical data.

The use of Agriculture Intelligent Systems (AISs) in Iraq has become popular among farmers. The greenhouse is a solution for plant growth, which uses an effective microclimate to simulate seasons and to use alternative energy sources like solar, thermal, and photovoltaic systems for microclimate control. Greenhouses are considered a successful solution with developments and achievements in the technology of this field. However, problems like high costs, difficulties in installation and maintenance, or the need for some procedures should be considered. Because Iraq is close to the equator (3669 km), it receives sufficient solar power. It also has large areas available for the building of solar greenhouse systems. The farmers need an affordable and functional smart greenhouse to enable and encourage them to use the environment efficiently. We intend to develop low-cost, accurate, and easy-to-use greenhouse systems controlled by artificial intelligence algorithms. Farmers will be able to control the greenhouse by using simple commands. Machine learning algorithms provide real-time and effective analysis that could support farmers in decision-making and provide relevant data for researchers and policymakers. AISs algorithms can lead to a sustainable and productive agriculture system. The system can be used in Iraq with sufficient government support and subsidy.

This study explores the neurological basis of emotions using a multi-method approach, analysing functional near-infrared spectroscopy (fNIRS) data obtained from a 26-channel device. Author’s primary objective was to examine the brain’s response to tasks that provoke emotional, imagery and affective reactions through the observation of hemodynamic changes in data. By applying data processing methods and techniques, cerebral activations corresponding to different emotional states were shown. This research enriches comprehension of how emotion and imagery tasks are processed by the brain and offers insights into aspects of brain activity during emotionally charged engagements.

Clustering in block Markov chains

This paper considers cluster detection in Block Markov Chains (BMCs). These Markov chains are characterized by a block structure in their transition matrix. More precisely, the n possible states are divided into a finite number of K groups or clusters, such that states in the same cluster exhibit the same transition rates to other states. One observes a trajectory of the Markov chain, and the objective is to recover, from this observation only, the (initially unknown) clusters. In this paper we devise a clustering procedure that accurately, efficiently, and provably detects the clusters. We first derive a fundamental information-theoretical lower bound on the detection error rate satisfied under any clustering algorithm. This bound identifies the parameters of the BMC, and trajectory lengths, for which it is possible to accurately detect the clusters. We next develop two clustering algorithms that can together accurately recover the cluster structure from the shortest possible trajectories, whenever the parameters allow detection. These algorithms thus reach the fundamental detectability limit, and are optimal in that sense. Copyright © 2017, The Authors. All rights reserved.

This paper deals with the problem of signals filtering using hybrid filters. Such solutions may prove to be especially beneficial in the context of biomedical signals filtering where the signals’ amplitudes are typically not very high and they can be easily affected by different kinds of disturbances. Having a number of different types of filters tuned for some specific purposes we will show how the best filter choice is affected by selecting one ML model over another.

Learning dynamical systems using local stability priors

arXiv

引用

arXiv 2020年

作者： Mehrjou, Arash Iannelli, Andrea Schölkopf, Bernhard Empirical Inference Department of Max Planck Institute for Intelligent Systems Tübingen Germany Department of Computer Science ETH Zürich Faculty of Electrical Engineering Zürich Switzerland Department of Electrical Engineering Automatic Control Lab ETH Zürich8092 Switzerland Empirical Inference Department of Max Planck Institute for Intelligent Systems Tübingen Germany

A coupled computational approach to simultaneously learn a vector field and the region of attraction of an equilibrium point from generated trajectories of the system is proposed. The nonlinear identification leverages the local stability information as a prior on the system, effectively endowing the estimate with this important structural property. In addition, the knowledge of the region of attraction plays an experiment design role by informing the selection of initial conditions from which trajectories are generated and by enabling the use of a Lyapunov function of the system as a regularization term. Numerical results show that the proposed method allows efficient sampling and provides an accurate estimate of the dynamics in an inner approximation of its region of attraction.
