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 small-signal 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 small-signal 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.
