Dynamic Control Design Based on Limited Model Information
2011 (English)In: Proceedings of the 49th Annual Allerton Conference on Communication, Control, and Computing, 2011, 1576-1583 p.Conference paper (Refereed)
The design of optimal H_2 dynamic controllers for interconnected linear systems using limited plant model information is considered. Control design strategies based on various degrees of model information are compared using the competitive ratio as a performance metric, that is, the worst case control performance for a given design strategy normalized with the optimal control performance based on full model information. An explicit minimizer of the competitive ratio is found. It is shown that this control design strategy is not dominated by any other strategy with the same amount of model information. The result applies to a class of system interconnections and design information characterized through given plant, control, and design graphs.
