Frequency-domain analysis of self-excited oscillations for a class of multivariable relay systems

This paper investigates certain complex oscillatory phenomena taking place in multivariable relay control systems. A frequency based approach is applied, by making use of such tools of frequency-domain analysis as the Locus of a Perturbed Relay System (LPRS) and transfer properties analysis via the equivalent gain concept. As the novelty, we provide… CONTINUE READING
