This paper solves the problem of synthesizing optimal control for complex nonlinear dynamic objects. Such problems often arise in various engineering applications such as robotics, mechatronics, and aerospace. Examples of such problems include the computation of the optimal flight path of an aircraft, manipulator control, and control of industrial applications. In most real-world applications, the control object is a high-order nonlinear dynamical system, and the parameters may be uncertain or vary over *** and iterative methods of optimal control synthesis are known;however, such methods are not applicable in the case of high dimensionality of the object "curse of dimensionality"and have poor convergence. In this paper, a new approach to solving the problem of program control synthesis based on the use of neural network controller is proposed. The loss function is formulated based on an adapted set of necessary optimality conditions derived from the maximum principle and approximation of the Hamilton-Jacobi-Bellman equation using neural networks. Compared to direct iterative methods, the method presented in this paper can efficiently obtain control from the state-space domain. The demonstration of the proposed method is carried out on a model example of constructing the optimal control of the output to the unstable position of the inverse pendulum, and the results of numerical simulation are given.

Space weather forecasting is of global interest, and its importance is well established in research community and recognized by government, industries and stockholders. Over the past years, many types of predictive models have been developed in the literature. There is a general agreement that forecasting models should not only provide point prediction but also inform the uncertainty associated with the prediction. This study presents a novel method bases on quantile regression and complex dynamic modelling for measuring uncertainties in space weather forecasting. The approach is implemented using Quantile regression and Nonlinear AutoRegressive Moving Average with Exogenous inputs (NARMAX) methods (for short the approach is called Q-NARMAX). The method is applied to Disturbance storm index (Dst) observations to examine its interpretability and capability for uncertainty analysis. Results show that the proposed Q-NARX model can produce excellent predictions of the Dst index, and meanwhile provides a measure for assessing the uncertainty in the forecast. The innovative integration of quantile regression, complex dynamic modelling and nonlinear system identification techniques enables the proposed work to have following attractive advantages and properties: 1) it can produce excellent prediction accuracy for space weather forecasting, 2) it uses transparent models to approximate (represent) black-box systems, enabling to interpret the dependent relationship between space weather indices (system outputs) and their drivers (system inputs), and 3) more importantly, it allows for uncertainty assessment and analysis of models and forecasts. © 2023 IEEE.

It has been revealed that in the conditions of small-scale production of discrete-analog filters on switched capacitors and ADC-drivers, it is most advisable to design high-speed operational amplifiers (OAs) based on the CBJT technological route and the MH2XA031 array chip, which allows operation in conditions of low temperatures and exposure to radiation. It has been established that most commercially produced O A s provide an average value of the slew rate (SR, up to 200 div 300 ~V / μ s). This is largely due to the limitations of the technologies used, and most importantly, to the irrational design of circuits. We study the maximum performance parameters of a CBJT OA with one integrating capacitor, which ensures the stability of the O A, and a differentiating transient correction circuit, which is implemented by connecting additional small capacitors to the original circuit. In this case, the S R of the O A increases by more than 500 times (up to 4000 ~V / μ s). © 2024 IEEE.

This study explores the application of deep learning techniques in recognizing emotional states from spoken language. Specifically, we employ Convolutional Neural Networks (CNNs) and the HuBERT model to analyze the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS). Our findings suggest that deep learning models, particularly the HuBERT model, exhibit significant potential in accurately identifying speech emotions. The models were trained and tested on a dataset containing various emotional expressions, including happiness, sadness, anger, and fear, among others. The experimentation involved preprocessing the audio data, feature extraction using Mel Frequency Cepstral Coefficients (MFCCs), and implementing deep learning architectures for emotion classification. The HuBERT model, with its advanced self-supervised learning mechanism, outperformed traditional CNNs in terms of accuracy and efficiency. This research highlights the importance of selecting appropriate deep learning models and feature sets for the task of speech emotion recognition. Our analysis demonstrates that the HuBERT model, by leveraging contextual information and temporal dynamics in speech, offers a promising approach for developing more sensitive and accurate SER systems. These systems have potential applications in various fields, including mental health assessment, interactive voice response systems, and educational software, by enabling machines to understand and respond to human emotions more effectively. The findings of this study contribute to the ongoing discussion in the field of artificial intelligence about the best practices for implementing deep learning techniques in speech processing tasks. © 2024 IEEE.

One of the problems of the modern theory of automatic control is the construction of verified mathematical models of objects of regulation. In some cases, obtaining such models is not possible. This paper discusses approaches to the use of neural networks as regulators. Due to the presence of the adaptivity property, neuroregulators in some cases show a better quality of control in comparison with classical ones. The most common architectures of neural networks and methods of their training are considered. A comparative analysis was carried out. The first stage in the design of neural network regulators is the creation of a neuroimitator. An example of the synthesis of a neural network simulator is given. The proposed scheme has been worked out on systems with saturation type limiters and a mechanical stop. © 2023 IEEE.

Autonomous electro-hydraulic actuators (AEHA) are widely used in industrial applications such as mobile manipulators, robotic exoskeleton, aerospace applications. AEHA has a number of significant advantages in relation to the electric drive: a high ratio of the developed force to the weight of the drive, compact dimensions of the autonomous drive, which are provided by the integrated layout of all elements of the electro-hydraulic system. However, the control of such systems becomes much more complicated due to the presence of significant nonlinearities in the control object. These include the non-linear characteristic of the switchgear, dry friction, and hard mechanical stops. All this makes it difficult to implement a control system based on classical controllers. The paper proposes a technique for synthesizing a controller that provides a sliding mode with compensatory neural network control for objects with an indefinite static characteristic. Using the direct Lyapunov method, we prove the stability of a feedback system. Numerical simulation results are presented to demonstrate the effectiveness of the proposed approaches.

The paper considers the problem of designing a regulator for a multicopter agent. Swarm control is organized by the thermal motion equivalent method. The idea of the method is the organization of the swarm agents' behavioral similarity to the atoms' thermal motion. This method makes it quite easy to organize the swarm agents' interaction and effectively solve problems: exploration issue in unknown environment, formation, tracking an object, mutual positioning of swarm agents. The key problem with the thermal motion equivalent method is the stabilization of the multicopter RMS velocity over time. Spontaneous growth or decrease in the agents' speed can lead to loss of swarm system controllability and mission failure. The paper proposes to synthesize a control system based on a linearized quadcopter model, which provides positional test oscillation stability of the aircraft to solve the above problem. The static state controller synthesized by the LMI method is used. Nonlinear model motion numerical simulation of a single UAV in a closed space is carried out in the paper. The results show the undamped multicopter oscillations. Multiple quadcopters are simulated in a confined space. The results show that the RMS agents' velocity does not change over time, which was required. © 2023 IEEE.

The article presents a new approach to creating a neural network simulator of a control object with a mechanical limiter, which allows you to identify the parameters of the limiter in real time. It is shown that the most effective way to identify such dynamic systems is to use neural networks based on ReLU activation functions. The effectiveness of the developed method is demonstrated by the example of the synthesis of stabilizing control for an aerodynamic pendulum using neural network predictive control. © 2023 IEEE.

The paper investigates the exploration issue by a swarm of quadrocopters. The thermal motion equivalent method is used for agents moving. The solution evaluation criterion is the swarm exploration time of more than 95% of an area square in case of limited inter-agent communication and partial agents' failure (lost). For comparison, a well-known rational-formed solution (called far as trivial) to the exploration issue is given. It consists of each agent disjoint trajectories planning at the swarm launch time. The trajectories' structure takes into account the agent field of view and covers the entire territory. The paper presents a mathematical model of the quadrocopter dynamics and thermal motion equivalent method. The exploration efficiency by a swarm using the thermal motion method depends, among other things, on the initial velocity vector direction. The paper presents the results of swarm simulation. The thermal motion equivalent method generally increases the exploration efficiency in conditions of limited communication and a decrease in the swarm number. However, in some cases, the exploration time is higher than in a trivial solution. © 2023 IEEE.

Breakthroughs in artificial intelligence and deep learning have had an impact not only on image and text processing, but also on robotics. Artificial neural networks (ANNs) are now used in automatic control systems. However, systems with a neural network controller lack theoretical guarantees of stability. Classical methods usually allow to obtain a controller with a proof of closed-loop stability for linear and linearized control objects. The proposed method allows to synthesize a neurocontroller that provides guaranteed asymptotic stability in the local region of phase space for objects that have constraints of various kinds. Also for the synthesized control system it is important the transition time, which meets the specified requirements. For this purpose, its optimization in terms of control time is provided by introducing an additional criterion. To guarantee the stability, an ANN-based Lyapunov function is synthesized together with the neurocontroller. Mixed Integer Programming (MIP) is used to confirm that the Lyapunov function satisfies the stability conditions. The result of solving the MIP problem either confirms that the stability conditions are met or is used to train the controller and Lyapunov function. As an example, the developed method was used to synthesize a tracking control system for a hydraulic drive. The obtained neural network system is compared by the tracking error with the linear-quadratic regulator (LQR). © 2023 IEEE.
