Abstract
An object of the invention is to provide a floating mobile object control system capable of causing a floating mobile object to stand still in a predetermined position with high precision or track a target trajectory with high precision, even under disturbances caused by waves, tidal current, etc.
A floating mobile object control system of the present invention capable of achieving the above object is a control system 1 for a floating mobile object 10, in which the floating mobile object includes: a main body part B that can be considered as a single rigid body constituting a part of the floating mobile object; an effector part E for generating a thrust for the floating mobile object; and a thrust transfer gate G for dynamically connecting the main body part and the effector part, the thrust transfer gate being adapted to be able to actually measure a thrust from the effector part acting on the main body part, and a measured value for the thrust from the thrust transfer gate G is used to obtain a thrust command to the effector part E (FIG. 4).

9. A control system for a floating mobile object, wherein,
the floating mobile object comprises: -
a main body part that can be considered as a single rigid body constituting a part of the thrust for the floating mobile object; and
an effector part for generating a thrust for the floating mobile object; and
a thrust transfer gate for dynamically connecting the main body part and the effector part, the thrust transfer gate being adapted to be able to actually measure a thrust from the effector part acting on the main body part, the main body part includes acceleration measurement means capable of measuring an acceleration of the floating mobile object, and a thrust command to the effector part is obtained by using;
an output from the acceleration measurement means of the main body part; and
a measured thrust valve from the thrust transfer gate. - View Dependent Claims (11)

13. A control system for a floating mobile object, wherein,
the floating mobile object includes acceleration measurement means capable of measuring an acceleration of the floating mobile object, the floating mobile object is arithmetically divided into: -
a virtual main body part that can be considered as a single rigid body constituting a part of the floating mobile object;
a virtual effector part for generating a thrust for the floating mobile object; and
a virtual thrust transfer gate for virtually connecting the virtual main body part and the virtual effector part, the virtual thrust transfer gate being adapted to be able to estimate a thrust from the virtual effector part acting on the virtual main body part based on an output from the acceleration measurement means, and a thrust command to the virtual effector part is obtained by using an estimated thrust value from the virtual thrust transfer gate. - View Dependent Claims (14)
