Abstract

The invention discloses a course control method for reducing invalid steering. The method comprises the steps of calculating a broad-spectrum wave filter coefficient; resolving a coefficient matrix required in the step of control component filtering; and carrying out a Kalman filtering state quantity calculation step. A result provides a step of calculating a basic control quantity and the step ofcontrol component filtering, because the basic control quantity and the filtering control component are calculated at the same time, large-phase lag caused by the fact that a band elimination filteris adopted for filtering firstly and then participates in calculation of the control quantity can be avoided, and therefore the control precision and stability of a ship course control system can still be guaranteed during filtering. After the calculated final rudder control quantity is sent to a steering engine control unit, effective control over the course can be achieved at a low steering frequency under the interference of stormy waves, and mechanical abrasion of ship steering engine equipment can be reduced.

Description

technical field [0001] The invention belongs to the technical field of ship automatic manipulation and control, and in particular relates to a course control method for reducing invalid steering. Background technique [0002] When a ship sails in wind and waves, it generates high-frequency yaw motion under the action of waves. In order to overcome the yaw, the conventional control method is to frequently turn the rudder to the left and right. Since the yaw frequency is much higher than the closed-loop bandwidth of the ship control system, the rudder to the left and right cannot suppress the high-frequency yaw motion and cannot produce effective control effects. , there are a lot of invalid steering in the control process. The rapid drop caused by frequent steering increases fuel consumption, and the resulting wear of the steering gear seriously affects the service life of mechanical equipment. Therefore, the problem of ineffective steering under wind and wave interference i...
