ROBUST–OPTIMAL STABILIZATION OF MARINE MOTION OBJECTS IN THE DYNAMIC POSITIONING MODE
Abstract:

The solution of the problem of improving the level and quality of control processes automation of marine movable objects (MMO) based on robust-optimal systems with variable feedbacks structure with requirements at maximum speed or minimum energy consumption in the conditions of uncertainty of dynamic models of MMO and the environment. The synthesis procedure of control functions that are implemented by using special variable feedbacks structures and allow solving the optimization problem of stabilization processes for defined optimality conditions is formed. robust circuit using an additional control signal generated by reference control system with variable feedbacks structure with incomplete apriority information about the model of MMO and the environment is synthesized. The simulation results showed that the proposed approach provides the minimum error values ​​and energy consumption.
