Abstract
In this paper, the bidirectional charger/discharger is developed on T-S fuzzy models. The circuit topology is constituted by Buck and Boost converters. The non-ideal element model is considered in the circuit. First, the state space average method is adopted to obtain the state equations of the bidirectional charger/discharger. Next, the output voltage controller is designed based on T-S fuzzy models. Moreover, the H ∞ performance index is added to suppress disturbances. And the control system stability is proved via Lyapunov theorem. Finally, the performance of the designed controller is verified by experimental results.
