Robust rudder roll reduction of container ship

Abstract EN

The aim of this paper is to apply the H∞ control on the container ship in order to reduce the roll effect and to stabilize its yaw using the rudder.

The main difficulty is to determine an admissible control law for the actuator in a way that it does not reach its saturation limit.

The new idea presented in this paper is to introduce the disturbance model in the design of the control law.

A cascade control structure is developed using H∞ control to compute the controller by taking into account the real condition of navigation.

Some simulation results illustrate the performance of this method.
