Robust coordinated control for ship power systems with SVC and power thruster loads

In this paper, a coordinated control problem of ship power system with SVC is addressed based on Hamilton function method. Firstly, a sufficient analysis for nonlinear modeling of Marine Diesel Engine Generator, SVC modeling, and propulsive motor load coupled nonlinear dynamic characteristics, secondly Hamilton realization of the modeling of the generator is obtained by a present state feedback technique, then, the controllers with SVC are designed to perform speed adjustment, excitation adjustment via Hamilton dissipation theory. The designed controllers have simple structure and tangible physical meanings. The simulation results show that the proposed control can effectively improve the transient performance of the power systems.
