dynamic equations for the ship benchmark model

Contents

Syntax

f = ship(x,u,w)

Description

Dynamic equation for the ship benchmark model (see Sec. 6 in [1]). The benchmark represents a 3 degree of freedom model of a container vessel. The system states are the x and y position, the orientation, the velocities in x and y in the vessel coordinate frame, and the angular velocity. Control inputs to the system are the forces and the moment acting on the ship.

Input Arguments

x

system states x (dimension: [nx,1])

u

control inputs u (dimension: [nu,1])

w

disturbances w (dimension: [nw,1])

Output Arguments

f

value of the dynamic function = time derivative of x
