Abstract It is very important to study medium frequency synchronous generator’s excitation control strategy and application in shipboard, for it can guarantee the safe operation of special equipment in high quality 400Hz medium frequency electrical system. In order to make the medium frequency synchronous generator terminal’s transient voltage restores as quickly as possible under the circumstances of suddenly increased and decreased load, this paper analyzes regulating property of the transient voltage of medium frequency electrical system and puts forward PID with current feed-forward controlling algorithm for medium frequency brushless excitation system, which compensates the exciter time constant to some extent, decreases its delaying effect, and increases the small signal response bandwidth of the excitation system. The simulation and experimental results verify the effectiveness of the proposed algorithm, which demonstrate that the proposed control system has good dynamic stability and steady-state performance.
