The potential of fractional order distributed MPC applied to steam/water loop in large scale ships

Abstract:

The steam/water loop is a crucial part of a steam power plant. However, satisfying control performance is difficult to obtain due to the frequent disturbance and load fluctuation. A fractional order model pbkp_redictive control was studied in this paper to improve the control performance of the steam/water loop. Firstly, the dynamic of the steam/water loop was introduced in large-scale ships. Then, the model pbkp_redictive control with an extended pbkp_rediction self adaptive controller framework was designed for the steam/water loop with a distributed scheme. Instead of an integer cost function, a fractional order cost function was applied in the model pbkp_redictive control optimization step. The superiority of the fractional order model pbkp_redictive control was validated with reference tracking and load fluctuation experiments.
