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.

Currently computer vision-based control systems are widely used. In such systems, procedures for detecting specified objects in images, calculating their characteristics and generating information for decision making are implemented. Mostly, in practice, the detected objects have the property of radial symmetry. For example, round markers are used as such objects, providing precise positioning in robotic systems. For their detection various methods of processing and analyzing images can be used. In this paper, we consider an approach based on the fast radial symmetry transform. As its application example, an algorithm for detecting centers of radially symmetric objects is considered. It is shown that this algorithm allows detecting the centers of radially symmetric objects in the conditions of noise that interfere with scene analysis in real conditions of the control systems operation. Besides, it shows how the algorithm is used in combination with the circles-detecting Hough method. The Hough method has a number of parameters, the setting of which is a time-consuming process as they are very sensitive to the size and location of the circles. The application of the algorithm for the circles' centers detecting makes it possible to refine the found circle by the degree of proximity of the center, obtained using the Hough method, to one of the centers obtained by fast radial symmetry transform. © 2019 IEEE.

In this paper, we consider identification of a linear system connected in parallel with the rate-independent hysteresis. Since the parallel system provides only the combined output of the two systems, it is required to extract the signal related to the target system from the observed data to identify the systems separately. In order to achieve this, we propose a system identification method, in which the identification experiment is performed twice with appropriately designed input signals. The inputs make the responses of the hysteresis identical in the two experiments, therefore the difference of the two observed outputs is related to only the target linear system. Then, the linear system is identified using the difference. The proposed method is applied to a rechargeable battery, whose output originates from the nonlinear and the linear elements: open circuit voltage with hysteresis and overpotential. The effectiveness of the proposed method is illustrated through a numerical simulation of the rechargeable battery. © 2018

In this paper, the fuzzy control of a mechatronic system will be studied. The mechatronic system is a special mobile robot (called two-wheeled mobile pendulum) that has two contact points with the supporting surface and its center of mass is located under the wheel axis. Due to the mechanical structure, the inner body (which acts as a pendulum between the wheels) tends to oscillate during the translational motion of the robot, thus the application of complex control solutions is essential in order to stabilize the dynamical system. In the first part of the paper the mechatronic system and the corresponding mathematical model are introduced, while in the second part the design and implementation of different fuzzy controllers are elaborated for the plant. The achieved control performances are analyzed based on simulation and implementation results. © 2016 IEEE.

Isoxazole and oxadiazole derivatives inhibiting 3-hydroxykynurenine transaminase (3HKT) are potential larvicidal candidates. This study aims to identify more suited potential inhibitors of Anopheles gambiae 3HKT (Ag3HKT) through molecular docking and molecular dynamics simulation. A total of 958 compounds were docked against Anopheles gambiae 3HKT (PDB ID: 2CH2) using Autodock vina and Autodock4. The top three identified hits were subjected to 300 ns molecular dynamics simulation using AMBER 18 and ADMET analysis using SWISSADME predictor and ADMETSAR. Replacement of alkyl attachment on C5 of isoxazole or oxadiazole derivative with a cycloalkyl group yielded compounds with lower binding energy than their straight chain counterparts. The top three compounds were brominated compounds, 2‐[3‐(4‐bromophenyl)‐1,2‐oxazol‐5‐yl]cyclopentane‐1‐carboxylic acid, 2-[3-(4-bromophenyl)-1,2,4-oxadiazol-5-yl]cyclopentane-1-carboxylic acid, 3-[3-(4-bromo-2-methylphenyl)-1,2,4-oxadiazol-5-yl]cyclopentane-1-carboxylic acid, and they had binding energies of −8.58, −8.25, and −8.18 kcal/mol in virtual screening against 2CH2 protein target, respectively. These compounds were predicted to be less toxic than temephos, a standard larvicide and more biodegradable than previously reported inhibitors. The three compounds exhibited a greater stabilizing effect on 2CH2 protein target than 4-[3-(4-bromophenyl)-1,2,4-oxadiazol-5-yl]butanoic acid, a previously reported inhibitor candidate with good larvicidal activity on Aedes aegypti. Further thermodynamic calculations revealed that the top three compounds possessed total binding energies (ΔG_bind) of −26.64 kcal/mol, −24.26 kcal/mol and −14.11 kcal/mol, respectively, as compared to −12.02 kcal/mol for 4-[3-(4-bromophenyl)-1,2,4-oxadiazol-5-yl]butanoic acid. These compounds could be better larvicides than previously reported isoxazole or oxadiazole derivatives and safer than temephos. © 2025 The Authors

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.

In this paper an anti-slip predictive controller is designed and implemented in order to control the rear wheels of a V-PRA (Variable Powered Rear Axle) vehicle. The control algorithm is EPSAC, a Model based Predictive control (MPC) strategy. It uses explicitly a model of the system for the prediction of the future system output, in order to calculate the optimal control input which will bring the system to a required setpoint. The main goals of this predictive controller were setpoint trajectory following, disturbance rejection and maintain overall the stability of the V-PRA vehicle. Although the process is nonlinear, being influenced by several parameters, linear discrete-time ARX models could be obtained based on system linearization around an operating point. An initial SISO controller was developed and tested, based on a Simulink model of the process. The control performances were tested successfully in presence of all kind of disturbances, denoting a robust controller. © 2011 IFAC.

Pole placement approaches for linear and fuzzy systems

Pole placement approaches for linear and fuzzy systems

6th International Symposium on Intelligent systems and informatics, SISY 2008

作者： Preitl, S. Precup, R.-E. Clep, P.A. Ursache, I.-B. Fodor, J. Škrjanc, I.

Polytechnical Institution Budapest Hungary Laboratory of Modelling Simulation and Control University of Ljubljana Ljubljana Slovenia

The paper investigates several pole placement methods in the linear case and suggests a new pole placement method by means of fuzzy linear equations. The linear methods concern the constant real part poles, the poles places on a circle, Butterworth configurations without and with the correction of the imaginary part, the pole-zero cancellation, and the poles placed on an ellipse. Low order systems are considered. The pole placement methods are compared by the digital simulation of control systems' behaviors with respect to the modification of the reference input. The conclusions are useful for continuous control systems, and they can be extended easily to digital control systems including quasi-continuous ones. ©2008 IEEE.
