Description

Method for tracking and controlling plane track of underwater robot
Technical Field
The invention belongs to the field of motion control of underwater robots, and particularly relates to a plane trajectory tracking control method of an underwater robot based on a finite time disturbance observer.
Background
The underwater robot is a typical strong nonlinear system, and the cross coupling among the degrees of freedom is easily interfered by the outside world under the complex marine environment. This makes the research on the trajectory tracking control of underwater robots still a huge challenge.
The Daiheng et al analyzes the reason for coupling according to the motion characteristics of the underwater robot and establishes a mathematical model of the underwater robot from the perspective of reducing the control coupling effect. By means of sliding mode control and further adding coupling terms into the control quantity, a trajectory tracking control law of the underwater robot in planar motion is designed, and robustness and anti-interference capability in the tracking process are met.
Under the interference of external disturbance, although the selected sliding mode control approach law with higher gain can compensate the external disturbance, the control input curve generates buffeting and loss due to excessively high control gain.
