The simulation runs quite slowly due to the fast switching dynamics in the original boost
converter circuit. The results show that the LPV model is able to capture the average
behavior nicely.
Conclusions
By using the duty cycle input and the resistive load as scheduling parameters, we were
able to obtain linear approximations of average model behavior in the form of a state-
space model array.
The resulting model array together with operating point related offset data was used to
create an LPV approximation of the nonlinear average behavior. Simulation studies show
