“…The dynamical system in which circuit equations are changed by a switching device such as a power conversion circuit is called a hybrid dynamical system [1][2][3]. The bifurcation phenomenon, where the current and voltage waveform behavior qualitatively changes due to changes in circuit parameters, specifically occurs when feedback control is applied to a power conversion circuit [4,5].…”

In this study, the first step we investigate the bifurcation phenomenon in a current-controlled step-up DC-DC converter with photovoltaic (PV) module using a one-dimensional circuit model. Specifically, we analyze the occurrence of the bifurcation phenomenon in this circuit model by defining the output voltage of the converter as constant and utilizing a PV module nonlinear output model with a relatively small number of parameters. Our results reveal the existence of a unique bifurcation structure in DC-DC converters with PV module, which has not been previously reported. We further elucidate the mechanism of occurrence through a stability analysis based on the brute-force method. The findings of this study contribute significantly to the development of circuit and bifurcation theory for current-controlled step-up DC-DC converters with PV module.First, we show a one-dimensional model of a current-controlled step-up DC-DC converter with a PV module and demonstrate the output characteristic model and circuit behavior of the PV module. Next, we explain the stability analysis method applied to this circuit model. Finally, we analyze the bifurcation phenomenon that occurs in this circuit model and discuss the mechanism of a unique bifurcation structure.

“…The parameter eigenvalue assignment approaches and evolutionary optimal algorithms are developed to find an optimal observer gain such that the residual signal is sensitive to the fault, but robust to disturbances. In the context of electrical faults that can occur in wind turbines, in Reference 8, the sparse recovery diagnosis (SRD) method is applied without the fault‐tolerant control to the diagnosis of a three‐phase DC‐AC power electronic inverter through a variation in the output filter phase's inductance and a variation in the DC‐link voltage.…”

This article deals with the design of an active fault‐tolerant control (AFTC) for a twin wind turbine consisting of two wind turbines mounted on the same tower. When one of the turbines is impacted by electrical faults, precisely a stator inter‐turn short circuits fault or a demagnetization fault, the sparse recovery diagnosis method is used for the detection, isolation and estimation of the active fault. An AFTC law is designed for the supervision of the faulty machine. Both methods, concerning diagnosis and control, are based on homogeneous theory and consequently converge in finite time. Simulation results highlighting the relevance of the proposed approach are also presented.
