In this paper is proposed a Data Driven control (DDC) law of a Permanent Magnet Synchronous Machine (PMSM) drive as an alternative to the Model Predictive control (MPC) strategy. The DDC method is designed for the inner control structure of the PMSM drive, the outer speed loop being employed by a classical linear PI controller. Thus, the DDC is based on build up a database of the relevant quantities as electromagnetic torque, speed, voltages and current, all obtained in steady-state regime with MPC strategy, being selected for the highest efficiency values for a given pair of speed and torque. The learning process of the DDC strategy by a mutidimesional interpolation method leads to obtain high performances in both steady-state and dynamic regimes, without any additional optimal current reference command. A comparative analysis done in Matlab simulation environment of the results obtained by both MPC and DDC control laws shows the effectiveness of the last strategies. The DDC method provide a robust optimal control under energetic constraints, being more suitable then the classical MPC law that can not offers reliable results for a large area of conditions in practice. © 2024 IEEE.

Explicit analytical expressions are derived for steady-state three-dimensional heat distribution in the cavity of a thermal accelerometer, based on generalization of the well-known analytical approach previously proposed by Hardee for the case of two concentric spheres,. The influence of the inner heat source geometry deviation from the perfect spherical shape on the device parameters is studied. © 2023 Concern CSRI Elektropribor, JSC.

This paper presents a control system for un-manned aerial vehicles (UAVs) that track deformable objects. Using Event-Triggered (ET) principles and Image Moments-Based Nonlinear Model Predictive control (NMPC), the suggested approach improves flexibility by triggering control changes in response to specific occurrences. The incorporation of Barrier Functions (BFs) enforces safety requirements, which are critical for negotiating uncertain terrains. The framework's implementation and testing on a UAV tracking deformable coastlines are intended to demonstrate its effectiveness in adapting to dynamic situations while adhering to safety limitations. © 2024 IEEE.

The paper explores the application of the ontological model of knowledge representation for the research of cognitive functions. A brief overview of the application of ontologies in the field of neuropsychology and neurophysiology is given. The relevance of the study is determined by the need for a comprehensive knowledge representation in the research field of cognitive functions based on the psychodiagnostic methods and analysis of EEG signals. An ontological model of knowledge representation for the subject area 'Cognitive functions' is described. The model includes knowledge about large-scale brain networks, EEG as a method for studying unconscious components of mental states, basic cognitive functions, and psychodiagnostic methods. The conceptual structure of the developed OWL ontology, its object properties and data properties are given. The presented ontology class structure is intended to collect knowledge about the patterns of brain activity and psychodiagnostic methods that can be used to diagnose mental states. The Protégé 5.5 editor was used to develop the OWL ontology. © 2022 IEEE.

With the development of digitalization and digital transformation processes, there is a concern of consolidating strategic control methods based on the balanced scorecard (BSC), data envelopment analysis (DEA) and logical-and-probabilistic approach, as well as creating on their basis a conceptual control scheme of organizational systems configurations. The question of forming a strategic map of digital transformation based on artificial neural networks is considered. In order to assess the effectiveness it is proposed to use a bunch of BSC-DEA methods. To assess the risk of failure to achieve the strategic objectives of the digital transformation of organizational systems, a bundle of MTSP-logic-probabilistic model was proposed. It is proposed to use a digital twin of the organizational system based on a simulation model to test the feasibility of control decisions in the context of digital incrementation in various situations of operation of the organizational system, at various stages of the intra-configuration cycle. © 2022 IEEE.

This paper presents a distributed setting of model predictive control (MPC) to manage linear multi-agent systems consisting of coupled subsystems. Specifically, local controllers can work in coalitions to improve performance and handle plug-and-play events. This study provides insight into a coalitional MPC strategy based on optimized tubes that handles plug-in and plug-out subsystems. Moreover, we explore an inherent robustness gap to absorb disturbances not covered by the tubes without having to group local controllers. A comparison of our approach with centralized and decentralized MPC is reported using an illustrative example.

In this work, an algorithm for route discovery in Cellular IP networks using Particle Swarm Optimization (PSO), has been proposed. According to the proposed algorithm, out of many paths available from the gateway of the network to the final destination, the one that satisfies the desired QoS has been selected. Two important QoS parameters, path loss and processing time at the router (Base Station), have been considered. The experimental results for both the QoS parameters reveal efficacy of the proposed algorithm. © 2022 IEEE.

The paper deals with a new algorithm for controlling a multi-phase buck DC-DC converter. The principle of its control is explained in detail using a flowchart. It is based on the continuous change of the converter topology using the number of its currently controlled phases depending on the size of the input power. In connection with this, its microprocessor control is also mentioned. The whole issue is explained on the design, simulation and measurement of a laboratory sample of a four-phase buck converter. © 2023 IEEE.
