Experimental dynamics of electromechanical pulse energy conversion systems

This paper develops methodology in the experimental research of the dynamics of electromechanical pulse energy conversion systems (PECSs) through the example of the dc electric drive with pulsewidth-modulation (PWM) control. The universal structure of the experimental plant was developed, which allowed the production of experimental bifurcation diagrams, time-series data, and phase-plane projections with variation of PECS controller parameters as well as load parameters. The approach to the experimental parameter identification (measuring) of the dc electric drive with PWM control was proposed. The adequacy degree of typical simplifications of electromechanical PECS mathematical models was studied both experimentally and theoretically.
