method and controller for modellpru00e4diktiven scheme of mehrphasigen dc / dc transformer

摘要

for a simple feasible procedures for modellpru00e4diktiven scheme of dc / dcwandlers, and a corresponding controller, the programming of the modellpru00e4diktiven system in large pru00e4diktionshorizonten quickly enough can be solved, it is provided that the opti mierungsproblem two optimization problems will be dividedby the control unit (10), a modellpru00e4diktive ausgangsgru00f6u00dfenregelung and modellpru00e4diktive drosselstromregelung are implementedwith the ausgangsgru00f6u00dfenregelung the strands of the mehrphasigen dc / dc converter (12) to a single strand are combined and it zeitdiskretes zustandsraummodell is created and the ausgangsgru00f6u00dfenregelung on a first cost function (j) of the optimierungsproblems d he ausgangsgru00f6u00dfenregelung the input voltage (uv.(k + 1) of the next abtastschrittes (k + 1) for the single strand pru00e4diziert the drosselstromregelung as default is specified and the drosselstromregelung thereof by means of a second cost function (ji) of the optimierungsproblems the drosselstromregelung for the next abtastschritt (k + 1) the necessary switch positions the switches (s1, s2, s3, s4, s5.s6) of the strands of the mehrphasigen dc / dc converter (12) is determined.
