A three fingered, multijointed robot gripper for experimental use is presented. The mechanics as well as the control architecture are designed for this special purpose. The gripper system provides the basic means in terms of position and force control to perform experiments about grasping and object motion in a useful way. The gripper will be used to develop and evaluate different approaches of stable grasping and object manipulation. First results of the control of the gripper on joint level as well as the cartesian behaviour of the fingers and some results and experiences with first grasping and manipulation experiments using the presented system are reported. © 1990 Institute of Electrical and Electronics Engineers Inc..

The research concentrates on the modernization issues of diesel-electric passenger locomotives TEP70. There is number of TEP70 locomotives in Baltic region that are used very rarely by their direct application but may as well be usable as freight locomotives. The main goal of the study is to change the tractive force of a TEP70 locomotive to be able to transport cargo in the Baltic region. Analysis of TEP70 working principles and load characteristics are presented. Based on the analytical model of locomotive, suggestion to replace the gearbox to increase locomotive pulling capability is proposed. Moreover, the paper presents calculation of the traction effort of TEP70. That kind of calculations are very important for motion planning and it should be done in order to avoid overloading during the working mode of the locomotive. © 2020 IEEE.

In recent years, there has been an increasing interest in renewable energy. Particularly, wind energy is gaining more and more popularity in many countries. However, the main obstacles to wind turbines usage are the vibration and noise close to wind farms. Therefore, this paper is focused on developing a new method for mathematical simulation of vibrations of a wind turbine in order to find out and reduce the vibration level. Particularly, low-frequency vibration of a wind turbine, composed of a tower and rotor in the out-of-balance condition is considered. The proposed method of vibration simulation is based on the theory of elastic beams and the general vibration theory. The calculations are made for a wind turbine VTR 50 Arctic. The results of the calculations are the displacement of the tower top and the stress at the tower foundation. Furthermore, it is worth emphasizing that the method is quite flexible. It allows adding complexity into the system, for instance, external loads such as wind pressure, aerodynamic loads, seismic loads or operational loads. © 2020 IEEE.

This paper presents the main faults of brushless DC motors and their diagnostic possibilities. Due to the popularity gain of such devices in the past decade, the maintenance and diagnostic of such machines is getting more important. As the machines are used in various applications, they are often critical parts of devices. Due to this, the unexpected failures of such machines are undesired and are to be avoided. The main faults of the machines are listed, some possibilities of their monitoring and diagnostics have been addressed. The necessity of further study has been pointed out. © 2020 IEEE.

The problem of providing smart manufacturing units, via supervisor control implemented in FIWARE, is studied. In order to investigate the problem at hand, an indicative manufacturing unit is considered, and the desired safe performance of the unit is achieved via a supervisory control architecture, being implemented in cloud computing environment. The model of the manufacturing unit is developed on the basis of the models of its sensors and actuators, in Discrete Event System (DES) form. The safe behavior of the unit is expressed in the form of nine rules. The rules are translated into nine regular languages that are realized as a set of proper supervisors. The supervisors are analytically determined and conducted in the open platform FIWARE, using all necessary smart data models and platform tools. © 2024 IEEE.

This research delves into the intricacies of achieving input-output decoupling for a class of uncertain linear parameter dependent systems. A combined approach is introduced, involving the utilization of a state feedback controller that incorporates both static and time-varying elements. The design of this controller aims to maintain insensitivity to uncertainties. The investigation establishes criteria for determining the feasibility of solving the robust input-output decoupling problem. Under these established conditions, a specific class of state feedback controllers is systematically identified as proficient in effectively addressing the stated problem. The proposed methodology entails deriving the controller and formulating solvability conditions to convert the original Parameter Dependent System (PDS) into an uncertain Linear Time-Invariant (L TI) system. Then an analytical presentation of a static state feedback controller is provided as a mean to resolve the input-output robust decoupling for the uncertain L TI system. The practical applicability of these findings is exemplified through successful implementation in a two-mass translation system, appropriately linked with a hydraulic actuator. © 2024 IEEE.

The problem of supervisor design for systems analyzed in cooperating pairs of subsystems is studied. The supervisors realize the cooperation using only sensor and actuator data of each pair of subsystems. The analysis of the system in cooperating pairs of subsystems covers a wide range of applications. Each cooperating ordered pair forms a master/slave relation between the sensor signals of the second element of the pair and the actuator of the first element of the pair. All possible cooperation relations are determined and investigated with respect to the avoidance of blocking and stuck to the initial states of the actuators. The system properties of the cooperation are formulated in a set theoretic scheme that allows the determination of the set of admissible cooperation rules. The present theoretical results are illustrated through one manufacturing application and one infrastructure application. © 2024 IEEE.
