“…Due to the lag of fast timescale information, stability analysis methods have been developed to describe these switching events mathematically, in order to determine the complex phenomena of bifurcations, chaos, and subharmonics [19][20][21]. In addition, studies on the control of power converters from the perspective of switching events have attracted researchers' attentions [22,23]. To address fast-scale nonlinearities, various stability analysis approaches have been applied on the piecewise linear dynamical systems, switched or hybrid systems, such as discrete map-based modeling [19], Floquet theory [24], Lyapunov-based methods [25], and trajectory sensitivity approach [26].…”
