Fixed Frequency Mode of a Two-Position Controller

Abstract

This paper deals with the mathematical analysis and simulation of dynamic properties of fixed frequency mode of a two-position controller. The principle of this mode lies in the fixed switching frequency of a controller. The switching algorithm of this mode is precisely calculated, which can increase quality and precision of a regulation process, in contrast with the comparative mode. The paper contains a mathematical analysis of this mode. Because the input signal is a square-wave waveform, a Laplace transform of the special signal waveform and subsequently, a Fourier analysis was used, and the output response of a system was derived.
