STUDY OF STABILITY OF BUCK CONVERTER WITH USAGE OF INTERVAL ARITHMETIC
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2016, Vol 63, Issue 272
Abstract
In the paper, the research of a buck step down converter with the usage of an interval arithmetic was presented. The interval arithmetic is the part of mathematics that is concerned with an uncertain data analysis. In this paper, the methods that aim to evaluate the stability of a system on the ground of the interval change of a parameter value were applied. The next studied aspect was the accordance of numerical calculations with results of measurements taken from the laboratory set. In the control process of the buck converter, the method of the perturbation of a control parameter was used. This method consists in the synchronization of the trajectory on which the system moves to the stable orbit. Choosing one of the system parameters the perturbed signal is added. In this way, the unstable periodic orbits inside of an attractor are stabilized by the low amplitude perturbation. The obtained results depicted on the high possibilities of the interval arithmetic in the researches of power electronic systems and analysis of their operation modes.
