Abstract

The current-mode controlled Ćuk converter, being a fourth-order nonlinear non-smooth system, does not lend itself to any simple analysis. The difficulty lies mainly in the complex modeling of the circuit needed to capture all the essential nonlinearities that occur in fast time scale such as border-collision bifurcation and chaos. This paper extends the Takagi-Sugeno fuzzy modeling approach to capture these fast time-scale nonlinearities. Non-smooth Lyapunov theory is employed to study the stability of the system and to locate the operating point at which the converter loses its stable period-1 operation.
