Kurzfassung englisch:
With battery emulators, development engineers can
test electrical drives on testbeds without the need for costly
battery prototypes. Furthermore, valuable time for battery pre-
conditioning can be saved. However, high quality battery em-
ulation is a challenge that requires a good battery model and
accurate emulation of the model with a controllable power supply.
A high-fidelity nonlinear battery model based on local model
networks is used. This allows the extraction of local linear models
for impedance emulation with a switch model DC-DC converter.
Local linear battery models and a model of the converter are
combined to a prediction model which is used for designing a
model predictive controller. In contrast to existing impedance
emulation schemes with cascaded feedback loops, the virtual
impedance is included in the inner voltage control loop in order
to achieve the highest possible bandwidth. Owing to constrained
optimal control, this is achieved while respecting control variable
constraints and inductor current safety limits. Experimental
results show the effectiveness of the proposed battery impedance
emulation scheme.
