Abstract EN
The pressure control for a liquid nature gas (LNG) ship is vital for the cargo handling system which is a nonlinear, unstable, and controllable complex system accompanied by the dynamics of time delay.
To improve the control effect, this article proposed a robust controller based on closed-loop gain shaping algorithm by mirror-mapping approach.
In addition, the complete mechanism models for the system are established to predict the changes of temperature, pressure, and liquid inventory in the cargo tank.
The heat exchanges and evaporation of liquid are also considered.
By collecting the data from the LNG ship “Dapeng,” the system models are validated.
At the same time, the comparative experiment is introduced to verify the reliability and effectiveness.
The scheme has been compared with the 2-DOF structure control law of modified Smith predictor.
The comparative experimental results show that the scheme proposed in this note has a strong disturbance rejection ability and steady-state performance.
The controller designed in this note has advantages of simplified construction method, satisfactory control effect and robustness.
