Abstract :
Bernstein and Haddad (1989) considered the problem of minimizing an entropy functional subject to an H∞ performance constraint. Since the entropy is an upper bound for the H2 cost, there remains a gap between entropy minimization and H2 minimization. A generalized cost functional involving both H2 and entropy aspects is considered here. This approach provides a means for optimizing H2 performance within H∞ control design
