Heating Model

AbstractIt is very important to design electrical machineries with high efficiency from the point of view of saving energy. Therefore, topology optimization (TO) is occasionally used as a design method for improving the performance of electrical machinery under the reasonable constraints. Because TO can achieve a design with much higher degree of freedom in terms of structure, there is a possibility for deriving the novel structure which would be quite different from the conventional structure. In this paper, topology optimization using sequential linear programming using move limit based on adaptive relaxation is applied to two models. The magnetic shielding, in which there are many local minima, is firstly employed as firstly benchmarking for the performance evaluation among several mathematical programming methods. Secondly, induction heating model is defined in 2-D axisymmetric field. In this model, the magnetic energy stored in the magnetic body is maximized under the constraint on the volume of magnetic body. Furthermore, the influence of the location of the design domain on the solutions is investigated.

This paper studies the problem of designing insensitive H∞ output-feedback controllers for linear discrete-time systems. The designed controllers are insensitive to additive/multiplicative controller coefficient variations. An LMI-based procedure, which is a sequential linear programming matrix method (SLPMM), is proposed to solve the considered problem which is a nonconvex problem itself. It is worth mentioning that the nonfragile control design method is adopted to obtain an effective solution for accelerating convergence of SLPMM algorithm due to the fact that a good starting point for the iteration is very important.

Project Method

The article discusses in detail the design method as a key tool in the educational process of higher education. Possible points of view on the nature of the project method are shown and argued, which allow integrating the body of acquired knowledge into the sphere of professional practice. The features of design technologies are disclosed and the advantages of its use in the training of environmental specialists are given, from the point of view of professional development of this category of specialists. The article is devoted to the actualization and significance of environmental education, with the aim of forming environmental awareness and educating the population, for processing sustainable development of society. One of the important directions associated with solving environmental problems at the present stage is environmental education and upbringing of the younger generation, namely the project method. Environmental education both in the world and in Russia is considered today a priority area of training and education of students at all levels of education. We have substantiated the relevance and relationship of environmental education and upbringing, disclosed their essence, objectives, content, principles, forms and methods of work; the analysis of the state is given, the mechanism of elaboration of certain aspects of the problem is characterized, etc. Achieving sustainable development and environmental safety of territories, solving global environmental problems, is impossible without the foundation of the foundations of a culture of environmental management and environmental education of the population. The project-method used by us in the training of specialists in the field of ecology has shown high efficiency in the formation of practice-oriented competencies of the graduate.
