The study of H/sup /spl infin// controller of flapped fin service system

This paper proposes a method to design the flapped fin service system using the H/sup /spl infin// control theory. The problems are solved that the flapped fin service system doesn't match the H/sup /spl infin// control theory because of the characteristics of flapped fin service system. At the same time, a new method is proposed to solve the problem of H/sup /spl infin// disturbance restrain.
