✦ Synopsis

Results of a novel benchmark study, tn which invesugators did not know the true systems are surveyed. Soluuons proposed by nine research teams highhght control design issues and the mterplay between robust and adaptive control Key Word~--Adapt~ve control, benchmark, robust control, time-varying systems, uncertain systems Al~tract--Commonly, partiopants of benchmark studies in control are supplied with knowledge of the true system to be controlled Exact knowledge of the plant, however, tends to influence the choice of tumng variables and d~scourages legmmate use of estimated or guessed informatmn This paper reports an alternative benchmark, in which partlopants did not know the true system, which was supplied in the form of scrambled slmulatmn code The paper describes the problem statement, reveals the true system and surveys the results obtained by nine different research teams Their approaches include indirect and direct adaptive control, model reference adaptive control, adaptive predictive control, H® robust control and robust stabdlty degree assignment The results display the trade-offs inherent in the different approaches and highlight the interplay between robust and adaptive control *
