Minimum entropy controller as a mixed H2/H controller: the time-varying case

Marc A. Peters, Pablo A. Iglesias

Research output: Contribution to journalConference articlepeer-review


An interpretation of the entropy, defined for discrete-time time-varying systems, is presented. The interpretation shows why minimum entropy controllers have an advantage over other H controllers, in the sense that the difference in norms of the input and output signals are relatively high for signals not equal to the worst-case one. Moreover, it is shown that minimizing the entropy results in relatively low quadratic cost, which indicates why minimum entropy controller are good mixed H2/H controllers.
