## Abstract

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 H_{2}/H_{∞} controllers.
