碩士 / 國立海洋大學 / 航海技術學系 / 82 / Course-Keeping is very important for a ship under sail. The
purpose of this thesis is to design a parametric state-feedback
controller in the economic energy consumption with respect to
the rudder and by adjusting the free parameters in the state-
feedback law in order to achieve optimal operation with respect
to some control purpose, such as robust stability. This thesis
is concerned with the minimum loss under steady sail without
external disturbance as a performance index of the system. A
set of reference poles which reflects the best pole locations
are obtained from LQR theory. This set is then used to design
the linear parametric state-feedback law in the pole- placement
problem. Multivariable generalization of Ackermann's formula
and the method of parametric hypothetical outputs are utilized
so that the problem of parametric state feedback law can be
obtained via the theory of hypothetical loop-decoupling.
Therefore, by adjusting thses effective free parameters,
minimum rudder energy responding to initial deviations with
respect to heading and rolling of the ship can be achieved.
