Control of multiple modular DC-to-DC power converters in conventional and dynamic sliding surfaces

Autonomous systems of electric power supply consisting of one common primary source of electric power supply and a set of multiple modular switched-controlled secondary sources of electric power supply (DC-to-DC power converters) are considered. The problem of the stabilization of the voltages transformed by the multiple modular switched-controlled secondary sources of electric supply is formulated and solved in conventional and dynamic local sliding surfaces. The robust decoupled linear desired behavior of the stabilization errors of the transformed voltages is guaranteed in local sliding modes. The desired quality of the voltage stabilization is achieved in dynamic sliding surfaces without measurement or estimation of disturbances (load currents).
