摘要：

This work presents the synthesis of fuzzy controls based on Linear Matrix Inequality (LMI) for DC-DC converters. Concretely, the paper proposes a linear-piecewise continuous control for a buck-boost converter which optimizes the decay rate of state variables under pole placement constraints and duty-cycle limitation. Based on a Takagi-Sugeno model of a buck-boost converter for a determined interval of operation, the paper describe the LMIs which take into account quadratic stability, closed-loop pole region and control signal bound. The procedure derives the control law by solving the LMI set using standard optimization algorithms on MATLAB. Some simulations illustrate and verify the correctness of proposed control design method, also a comparison with a common linear control law is provided.
