Performance Analysis of Ship Tracking using PID/Predictive Controller

Accurate ship navigation is very essential forsaving fuel as well time. In order to achieve accurate tracking inunmanned ship navigation various controllers like PID,Predictive and Adaptive controllers are used. Each one ishaving its own merits and demerits but the Predictive controllerprovides better tracking. The only major limitation ofPredictive and Adaptive controllers is that they arecomputationally heavy. In order to reduce the computationaltime, researches have come up with various matrix inversiontechniques [7]. In this work an attempt is made to evaluate theperformance of PID and Predictive controllers in terms oftracking efficiency and computational time. Computationalresult evaluated using mat lab shows that Predictive controllerwith matrix inversion technique provides better tracking andtakes less time.
