Stability Problems in Designing Aggregated and Distributed Systems of Secondary Power Supplies

Small-signal simulation applied to calculation of the parameters of nonlinear dynamics processes control systems for DC/DC converters

“…From the control theory perspective, such converters are a nonlinear dynamic system, which determines the features of calculating their control system parameters. At present, there are quite a lot of works devoted to designing such systems [1][2][3][4][5][6][7][8][9] and considerable experience has been accumulated in the relevant field, which makes it possible to generalize the results obtained.…”

“…On the one hand, small-signal modelling is the most frequently used in their calculation, when a system of differential equations is linearized in a small neighbourhood of a equilibrium point, then small-signal transfer functions are constructed [1,[4][5][6][7]. In this case, equilibrium point stability of the system, which it enters after finishing the transient process, is ensured.…”
