“…In the interest of keeping the model simple, and inspired by the work in [5], we neglect the combustion delay and assume that the dynamics of the fuel actuator constitutes the essential dynamics of the engine.

“…Most of the authors in this arena treat the two cases separately. For example, the authors in [5], and [6] proposed two different approaches to tackle the problem of controlling the Genset, but both of the works considered the propeller as part of the load since it is driven electrically. Our target, as a future work, is to put a model for this hybrid system in all modes of operation, then, design a supervisory power generation controller.…”

In some designs of power systems for marine vessels, large-size or medium-size Diesel engine(s) is(are) used to drive one synchronous machine to generate electricity, and the main propeller, simultaneously, through a gear box. Such systems are subject to disturbances that may affect performance and fuel consumption. The most important disturbances occur due to the propeller torque, and load demand on the electric network. In this work, a simplified state-space model is suggested for such systems based on well known models of each component. The model considers the dynamics of the shaft, Diesel engine, and synchronous machine with the propeller in their simplest models. The output voltage and torque coefficient were modeled as uncertain parameters. Then, exploiting feedback linearization, two controllers were suggested for the proposed model to regulate the rotational speed of the shaft. Firstly, by pole placement. The second is a robust controller by mixed H 2 /H ∞ synthesis. The results of the simulations of the proposed controller are presented and compared.

“…Now, if we would like to combine the action of the speed governor and the AVR, a state-space model is needed because of the nonlinearity of the system. Although the model (20) was used by Hansen et al (2001) to propose a controller for marine Genset, we believe that this model may not be sufficient for the following two reasons. First, the air dynamics are not taken in consideration.…”

A generating set (Genset) comprises a prime mover such as a Diesel Engine, and a synchronous generator. The most important controllers of such systems are the speed governor to regulate the engine or shaft speed and the automatic voltage regulator (AVR) to regulate the terminal voltage. The speed governor is a PID controller that uses the difference between the speed and its desired value as a feedback signal to change the fuel mass input by changing the fuel rack position. AVR is also a PID that uses the difference between the terminal voltage of the generator and its desired value, and changes it by manipulating the voltage of the field excitation circuit. Thus, the two controllers act separately. That is to say, if the speed varies from the desired value, the speed governor will react, while the AVR will not react as long as the voltage is stable, and vice versa. In this work, a control-oriented model is suggested for a Genset, and then a controller, that regulates the shaft speed and the terminal voltage, is designed by feedback linearisation. The proposed controller has two inputs: the fuel mass and the field circuit voltage. Simulations show that the proposed controller makes the two inputs act, simultaneously. Thus, any change of the speed e.g., forces the two input controls to react, in contrast to the ordinary PID controllers. Further, we discuss the robustness of the proposed controller to uncertainties and time delay.

Electrification of ship propulsion system with hybrid power systems created interest in modeling of all marine vessels. Reduction in the emission of green house gases, fuel consumption and efficient energy management with improved system dynamic performance is possible with hybrid power systems. With penetration of power electronic converters into power systems, ship board direct current distribution systems offer further more advantages such as space, weight saving and flexible arrangement of equipment. On board marine vessel consists of synchronous generator, energy storage system, fuel cell, photo voltaic array and induction motor drive. Power electronic converters are modeled through detailed model. Mechanical components are modeled with mathematical analysis approach. Power sharing among the proposed hybrid power system is observed in MATLAB/Simulink software.
