摘要
Recent papers have shown advantages of robust controllers compared to the controllers based on classical control theory. Further improvements in performance and stable operating range may be realized through the use of multiple robust controllers, but these are typically complicated to synthesize and implement. The complexity is somewhat relaxed for bumpless-transfer controllers, which have appeared in the literature as an ad hoc gain-scheduling control scheme. The approach is less conservative, easier to synthesize, and easier to implement than a gain-scheduled polytopic controller or other interpolation scheme, and has a larger operating range than a nominal controller. In this paper, an inverter connected to a microgrid is modeled as a linear parameter varying system and bumpless controllers are scheduled using polytopic coordinates and applied to inverters in a microgrid.
