The model of linear drive with redundant actuation and control system is designed to compare the energy efficiency of the different actuation type. The redundant actuation control system is optimized to increase the energy efficiency of the entire drive. Calculation with this model compares consumed electricity for each drive topology. The results can be used in the design of energy-efficient production machinery and equipment, which is the area of interest of so-called Ecodesign.

Most customarily used motor in the industries are induction motor due to its low cost, robustness and less maintenance. The change in the existing framework is necessary in order to make the motor more efficient one. This paper cast enlightenment about the PLC based 3 phase multi-starter control induction motor with energy efficient single control system. In order to start the engine's operation by its own power, starters are used. Various starters are available to initiate the 3-phase induction motor namely Direct On-line, Star-delta, autotransformer and rotor impedance. The employment of this PLC based techniques helps to increase the energy efficiency of the motor .The employability of PLC in this system is to help in the growth of automation. The hardware and software results of the multi starter control using single control systems are analysed

Deep rock burst accidents occur frequently and become increasingly serious. Further improving the effectiveness and accuracy of the prevention and control of rock burst, ensuring the safe and efficient production of mines, clarifying the basic causes of disasters, and refining the type of deep rock burst are the most important key links. Aiming at the problems such as unclear incentives and types and the lack of effective and targeted prevention measures of deep rock burst, taking Xin’an Mine as the research background, based on the energy theory, the coal and rock mass multisource energy unified equation was established to analyze coal and rock mass instability mechanism. According to the different degrees of participation of various factors, the types of deep rock burst are determined as three categories and four types, and the corresponding judgment criteria are proposed. The precise prevention and control system for the source of rock burst with Xin’an characteristics is proposed, successfully applied to the 8101 working face, which not only guarantees the safe production of the working face, but also achieves good economic benefits. The research results lay the foundation for improving the accuracy and precision of the prevention and control of deep rock burst and provide theoretical guidance for the safe and efficient mining of the mine.

The subject of this paper is the study of the use in practice of the components of the project portfolio in optimal condition. An important issue in the study of this project is the evaluation of the effectiveness of these components. Attention is paid to the portfolio of projects where it is possible to carry out continuous restructuring in accordance with the limited investment opportunities. The authors have developed energy-efficient methods of project management and control at all stages of construction. The role of the utility function in the formation of the investment portfolio is also considered. A model for calculating the indicators of the project portfolio is developed on the example of building a network of banks in Russia. This model allows you to avoid financial losses, evaluate your activities, and improve the efficiency and effectiveness of projects.
