Abstract
The problem of disturbance decoupling is formulated and solved for continuous-time linear systems in which feedforward of disturbance input and its derivatives is allowed. The problem of disturbance decoupling by preview control is also formulated for discrete-time linear systems and it is shown that these two problems are algebraically equivalent. The result is applied to the design of a disturbance absorber for an open bottom floating structure and a simulation study is carried out to demonstrate the effectiveness of the result.Keywords
