This paper introduces an advanced control strategy for bidirectional cascaded buck-boost (BCBB) converters in vehicle-to-grid (V2G) systems. By leveraging a comprehensive nonlinear model of the BCBB circuit, enhanced with a piecewise mapping function, the proposed methodology offers superior adaptability to varying operational conditions. Central to this approach is the utilization of a state-feedback linearization control scheme, effectively improving the system dynamics. MATLAB/Simulink simulations demonstrate the improved performance of the proposed method over conventional PI controllers across diverse scenarios. Experimental validation confirms its practical effectiveness, highlighting its potential for enhancing the integration of electric vehicles into the grid.
