Abstract

This paper is concerned with the design of PID controllers, which have similar features to the model-based predictive controller for ship autopilot. A PID type control structure is defined which includes prediction of the output and the recalculation of new set point using the future set point data. The optimal values of the PID gains are calculated using the values of gains calculated using unconstrained generalised predictive control algorithm. The proposed controller is applied to ship autopilot model and simulation results are compared with conventional and generalised predictive control solutions.
