Abstract :
A linear-quadratic-Gaussian/loop-transfer-recovery (LQG/LTR) controller is used for automatic steering of ships. Identification of the discrete-time system is based on Nomoto´s model and on the innovation model. The system is non-minimum-phase, which is the sampled version of the continuous system. The benefits of this controller are demonstrated by simulation results
