RMMAC: Robust Multiple-Model Adaptive Control

Prof Michael Athans (MIT)

Abstract

Dozens of books and hundreds of papers have been written on the topic of Adaptive Control starting at about 1965. Often, the research on adaptive control has been akin to the "search for the gold at the end of the rainbow". In spite of dozens of claims and counterclaims and myriad of polite and heated discussions (by "fuzzies" and "crispies" alike) we are a long way from having a practical engineering approach and solution to the adaptive control problem.

In this talk we overview some very recent promising developments to the so-called robust adaptive control problem using a novel architecture called "Robust Multiple-Model Adaptive Control (RMMAC)". We shall discuss its key characteristics and present several nontrivial simulations that demonstrate its superior performance. We also demonstrate situations in which it does not work quite well; these lead to suggestions for future research.
