This paper presents a robust control design methodology for a serial DC–AC converter based on 𝐻∞ synthesis and a MATLAB/Simulink modelling framework. A mathematical model of the converter is derived and linearized around a selected operating point to obtain a plant representation suitable for robust controller synthesis. Performance objectives related to output regulation, disturbance rejection, and control effort are formulated using appropriate weighting functions. An 𝐻∞ controller is then synthesized and evaluated under parameter variations and load disturbances. The results demonstrate improved robustness and dynamic performance compared to conventional linear control approaches, confirming the suitability of 𝐻∞-based design for power electronic converters operating under uncertainty.
