With respect to the engineering education there is a need for measuring the level of student’s creative potential to assess the educational results. Considering the approach realized in SRBCSS (Scales for Rating the Behavioral Characteristics of Superior Students) the present study initiates a new instrument developing a set of scales to estimate the engineering student’s creative potential in the areas of intelligence and creativity, motivation and will, productivity, as well as reflection. The solution considers the engineering specifics and can be applied at any stage of studying. It was tested while measuring the creative potential of engineering students.","PeriodicalId":240191,"journal":{"name":"2020 IEEE Problems of Automated Electrodrive.

The purpose of the research is the synthesis of controllers, testing, the choice of the structural scheme, parameters of the control and data processing system in the bench for the precision tuning of internal combustion engines. Based on a preliminary analysis of the system, taking into account the mechanical connection of the wheels through the main gear and the car differential, the nonlinear dependence of the electromagnetic torque on the current and retarder speed, and subsequent experimental results, two types of control object models are obtained – a third-order aperiodic transfer function and a fractional aperiodic transfer function of order 1.6. This allowed us to synthesize a family of controllers that ensure the operation of the bench in several modes – synchronization of wheel rotation speeds during engine acceleration; stabilization of reference speed when the engine torque changes; the mode of measuring the maximum power and torque of the internal combustion engine at a linearly increasing speed. The system with the PID-controller configured in MATLAB in the “Tune” package has the best performance, but the smallest overshoot and the best dynamic accuracy were ensured by the PIDIγ Iμ fractional-integral controller, with which the system is characterized by a fractional order of astaticism 1.6. Such a controller for each electromagnetic retarder has become the basis of the microprocessor-based control, data acquisition, processing, graphical display system, and will also be used to develop a similar bench for tuning the four-wheel-drive vehicle.","PeriodicalId":240191,"journal":{"name":"2020 IEEE Problems of Automated Electrodrive.

The rotor resistance changing is done by means of mechanical contacts. The presented work focuses on one of the cases of WRIM failure – overheating of rotor windings. This is mainly caused by the rotor circuit unbalance which resulted from misconfiguration of the rotor resistances (e.g. one of the resistors breaks open, mechanical contact fails to close, etc.). In the vast majority of drives with WRIM, its rotor currents are not monitored at all, and rotor unbalance is left “unseen” by the stator protection devices, causing WRIM thermal failure. The paper presents a motor protection device, which is able to detect WRIM rotor currents unbalance while using only stator current and voltage measurements. This allows to improve reliability of WRIM drives while maintaining low cost of protection device itself.","PeriodicalId":240191,"journal":{"name":"2020 IEEE Problems of Automated Electrodrive.

The proposed system of local positioning of mobile objects is based on the use of many base stations, which are used to determine the current coordinates of the object in space. To transmit information between base stations, it is proposed to use the technology of interaction between nodes used in wireless sensor networks. Thus, we get a scalable and reliable network of base stations. Guaranteed package delivery is a basic requirement for a local positioning system. The second important factor is the speed of message delivery. In this paper, we propose an algorithm for constructing an optimal delivery route messages, the simulation of its work was performed using the developed program in C#. The program allows you to get directions from an arbitrary base station to the main information collection module.

The use of irrigation water to cool an engine is safe against other technologies and this technology is always profitable. The efficiency of liquefied petroleum gas as an engine-generator fuel is moderate and depends on the ratio of fuel prices.
