Stability Control of Ship in Missile Firing Mission Using Model Predictive Control
Warships have a mission to defend themselves from enemy attacks. One of the weapons possessed is an air defense missile. When firing a missile, the ship receives an impact force. To restore the stability of the vessel due to the impact force, it is necessary to control the steering angle of the ship (rudder) in order to keep the yaw angle (or heading angle) in the desired condition. This work aims to implement a Model Predictive Control (MPC) control system to control the yaw angle of the ship during a shooting period. The results show that the MPC controller is able to drive the ship's heading angle to reach the reference angle. From two scenarios, the best performance is achieved when prediction horizon equals 25 based on Root Mean Square Error (RMSE).
