Abstract

---

The design and the implementation of a TS fuzzy modeling and control applied to two level and three level DC-DC converters that operate in large-signal domain are presented. Unlike conventional fuzzy controller design which addresses only smallsignal system control, the proposed approach ensures good performances and high accuracy of the modeling and control system over the whole operating space. This links to: i) The ability of dealing with the nonlinearity present in the conversion ratio of the DC–DC converters by means of a Takagi–Sugeno fuzzy approximator; ii) The skill to automatically derive the corresponding smallsignal model for the converters under a wide range of operating conditions using TS fuzzy modeling approach. According to the TS fuzzy technique, the proposed control techniques vary from self-tuning PI control to the state-feedback based control using Parallel Distributed Compensation (PDC) concept. Experimental results using dSPACE DS1104 board, two level and three level DC-DC converters, for different operating conditions, illustrate the efficiency, the robustness and the flexibility of the proposed approach.
