Bifurcation approach to condition monitoring: Application to pulse energy conversion systems

A new approach for forecasting and detecting emergencies by condition monitoring, based on the bifurcation analysis, is proposed using an experimental study of pulse energy conversion systems. The proposed approach uses online monitoring of ‘dangerous’ bifurcation boundaries in a system parameter space. It enables it to identify ‘dangerous’ bifurcation situations potentially associated with emergencies on-line, using systems state vector analysis. The approach is applied to a DC electric drive with energy pulse modulation. The results of the bifurcation analysis using mathematical and physical models as well as experimental evaluation testing the adequacy of the bifurcation analysis are discussed. This approach also has an application for the calculation of spare requirments.
