Integrated coordination control of marine generators based on Hamilton function approach
基于Hamilton函数方法的船舶发电机组综合协调控制

The propeller load is a crucial factor affecting the transient stability of the marine power system. This makes the stability study of marine power system more challenging than that of the land power systems. Based on Hamilton control theory of energy, an integrated coordination control of generator excitation and speed regulation is investigated for the marine power systems with propeller loads. After analyzing the nonlinear coupling between the marine diesel generator and the propeller load, we develop the stabilizing integrated control law by constructing the Hamilton energy function. Being different from other existing control laws, this one explicitly provides the functional relation between the propeller revolution and control performances. Simulation results show the effective suppression of the impact from the propeller load to the system performance.
