Experimental bifurcation tuning oriented to real-time analytics of pulse system fault dynamics

Abstract : Pulse control remains to be considered among promising engineering solutions from efficiency criteria connected with energy conversion processes. While operating the process, the pulse energy conversion system (PEC-system) structure changes following a preset control algorithm. These structural changes lead to the variety, complexity, and uncertainty of nonlinear phenomena, and not all of such phenomena can be originally simulated by computer modeling. Experimental bifurcation analytics could be a reasonable tool to support revealing evolutional degradation. However, usually, such analytics means too much additional expenditure on both experimental tests and expert opinions. The bifurcation tuning focuses on the practical viewpoint when it seems interesting to try to adapt the scientific results to particular practical solutions on operating regime evolution only. The paper promotes this idea. Namely, we discuss the following point: whether it is possible to collect such existing research tools, which could cover the main required procedures for real-time fault analytics. Here we restrict the notion of “fault” by the loss of operating process stability under pulse-width modulation only. Thus we discuss tools for detailed experimental bifurcation analysis and propose the basic technology to find such an optimal solution when the necessary evolutional picture could be got under formalized experimental testing. We believe that the presented results could help develop the methods of monitoring and fault detection in application to PEC-systems to more or less extent.
