Abstract
The paper suggests a method formotion generation and feedback stabilization of a dynamicalmodel of an underactuated ship with 3 degrees of freedom and 2 controlinputs with a presence of lumped enviromental forces acting on themodel. If the geometrical path for ship motion is given, the methodsuggests a description of all feasible motions of the model along thispath. It is shown how to desing controller to counteract enviromental forces remaining on path.
