The aim of this article is to inform reader about the development steps and practices which were used during the development of a control system of a fuel metering pump. The aim of this development was to design a cntrol system for a BLDC motor in accordance with rigid aviation standards and verify new development practices and tools alowing faster and simpler certification. The development covers such steps as definition of first requirements, preliminary design, system modelling and simulation, detailed deisgn, verification and testing. Given description intruduces reader to mandatory practices and procedures which are obligatory for successful certification of developed control systems. In addition, the first results measured on an evaluation sample are presented. and Obsahuje seznam literatury
The article focuses on a list of options for using interpolations, often referred to as interpolation of higher types. The article pays attention to several representatives of control systems. The issue is also conceived in relation to the preparation of the NC program by CAD/CAM, where the data is prepared for control systems. The available functions of CAD/CAM systems are very diverse. The preparation of the NC program is also related to the issue of postprocessors and therefore they are mentioned in the article as well. Let this article be a basis for those who are interested in the creation of NC programs using non-standard interpolations and serve as an introduction to this issue. and Obsahuje seznam literatury
In this paper, we study the problem of stabilization via homogeneous feedback of single-input homogeneous polynomial systems in the plane. We give a complete classification of systems for which there exists a homogeneous stabilizing feedback that is smooth on R2∖{(0,0)} and preserve the homogeneity of the closed loop system. Our results are essentially based on Theorem of Hahn in which the author gives necessary and sufficient conditions of stability of homogeneous systems in the plane.
