The development of modern IT technologies and resources, offer in many economic-industrial applications, efficient solutions for planning and managing of specific activities. New research directions in the field of management and optimization of supply-customer (SC) systems are defined and evaluated. The paper proposes a management model based on a causal graph structure, which expresses the connection and interdependence between the two entities involved in the specific activities of the field, the suppliers of goods and services and the consumers of these goods and products. Information related to production and storage capacity, up-to-date requirements for customer needs, delivery planning, production and consumption dynamics are considered. The transport between the actors involved in the system is an important component with weight in the costs of supply-sale activities. The optimal solution for the supply-customer transport system is proposed based on different strategies of game theory.

Safety PLCs are commonly used in industrial applications to implement safety functions. However, they almost always require output circuits for power adaptation between the safety PLC and the controlled technology. This power adaptation also affects safety. This paper focuses on the design of output circuit architecture that allows the use of diagnostic testing to improve safety, even during continuous operation where diagnostic testing is not usually possible.

The paper deals with the design and implementation of safety functions for a CNC milling machine. It is a relatively small CNC milling machine that does not pose a great danger to trained persons. Because it is used in areas where even untrained persons can come into contact with it, it was necessary to implement a safety system that implements safety functions preventing accidents when entering the dangerous zone of the CNC milling machine. The safety system is implemented based on a safety PLC and the sensors are designed using a two-channel architecture to meet the required SIL (safety integrity level).

This paper investigates selective power transfer between users located in a power distribution line by the implementation of a multifrequency bus. Multifrequency power distribution implies the generation of additional power channels on the same distribution bus by combining two or more power transfers at different frequencies. To analyze the feasibility of this proposal, a point-to-point power transfer using a second frequency power channel in a power distribution line is proposed. To do that, an AC switching power source is required to inject that power in the grid, and an AC switching power sink to extract it and deliver it to the receiver load. Essentially, AC switching power injectors and extractors have the same circuit that consists of two inverters, one behaving as a voltage-source/sink and the other working as a current-source/sink. A proof-of-concept demonstrator is being developed to test the operation of the injector/extractor conversion block and the performance of the multifrequency bus at grid’s third harmonic.
In order to enhance the anti-disturbance capability of voltage fluctuation during microgrid island operation, a decentralized dynamic disturbance compensation control strategy for multiple inverters in parallel based ...

Differential signals are key in controlengineering as they anticipate future behavior of process variables and therefore are critical in formulating control laws such as proportional-integral-derivative(PID).The practical challenge,however,is to extract such signals from noisy measurements and this difficulty is addressed first by *** in the form of linear and nonlinear tracking differentiator(TD).While improvements were made,TD did not completely resolve the conflict between the noise sensitivity and the accuracy and timeliness of the *** two approaches proposed in this paper start with the basic linear TD,but apply iterative learning mechanism to the historical data in a moving window(MW),to form two new iterative learning tracking differentiators(IL-TD):one is a parallel IL-TD using an iterative ladder network structure which is implementable in analog circuits;the other a serial IL-TD which is implementable digitally on any computer *** algorithms are validated in simulations which show that the proposed two IL-TDs have better tracking differentiation and de-noise performance compared to the existing linear TD.

In recent years, the rapid development of autonomous system technology has increasingly positioned it as a crucial player in modern transportation. Appropriate speed planning emerges as one of the key elements for achieving safe and efficient autonomous system operations. Speed planning not only requires adherence to road speed limits and ensuring safe distances to avoid collisions but also necessitates consideration for ensuring passenger comfort. This paper proposes a method that restricts acceleration and jerk to achieve smooth speed control, enabling autonomous system to emulate the driving style of human drivers. Utilizing visual SLAM for feature extraction and matching on images, a sparse point cloud three-dimensional map of the environment is constructed. The recorded path is tracked using the Pure Pursuit algorithm. Finally, this paper will validate the proposed approach through an embedded system deployed in a real vehicle. The integration of visual SLAM and smooth speed control technology realizes a real-time and smooth autonomous system, providing a safer autonomous system experience.
