Optimal Control of Double Star Synchronous Machine for the Ship Electric Propulsion System
نویسندگان
چکیده
this work focuses on modelling, optimal control and numerical simulation of the ship electric propulsion system provided by a double star synchronous machine. The in-depth analysis of the operation of the propulsion system of the vessel allowed us to model elements of the propulsion system. Thus, a non-linear global model was obtained describing the operation of the entire propulsion system. The nonlinear model is linearized about the nominal operating point on which an optimal control using a ship speed state observer is applied. The performances and the effectiveness of the studied approach applied to a ship electric propulsion is highlighted through numerical simulation, using Matlab/Simulink, to ensure perfect tracking of ship speed. Keywords— Optimal control, Sate observer, Double star Synchronous motor, Ship electrical propulsion system

متن کاملApplication to Adaptive Control to Synchronous Machine Excitation
Self-tuning adaptive control technique has the advantage of being able to track the system operating conditions so that satisfactory control action can always be produced. Self-tuning algorithms can be implemented easily. Because the power systems are usually time varying non-linear systems and their parameters vary, adaptive controllers are very suitable for power systems. Characteristics of a...
