This paper presents the design and simulation of robust control for DC/DC multi-converter based on terms like differential flatness and active disturbance rejection. The main goal of the control law is to obtain a regulated output voltage for each converter in cascade, and a balance of currents for parallel converters. The controller must actively reject the endogenous and exogenous disturbances, i.e. maintaining a robust output. The effectiveness of the proposed controller was verified by computer simulations using MATLAB/Simulink.
