Abstract: This paper aims to obtain mathematical model of the full-scope roll motion for DTMB 5415 Combatant Warship and provide an optimal control by using Active Roll Fin Stabilizer (ARFS) structures. The mathematical model of the warship and the actuator model have been obtained in according to literature. Furthermore, the damping term parameters in the equation of the roll motion have been extended by comparing experimental and numerical studies in the literature. In order to ensure the required control moment and roll damping ratio, ARFS section (NACA 0015) has been selected and the fin structure is designed. As a controller method, actuator saturated Linear Matrix Inequality (LMI) Based State-Feedback H ∞ Optimal Controller has been used to stabilize the roll motion of the DTMB 5415 Combatant Warship with ARFS Structure. Moreover, the results are compared with the criteria that military ships should comply. Significant decrement (above 90% for different sea states) of the ship roll amplitudes have been occurred and met the standard of STANAG 4154. Fin angle saturation limit of 24 degree has not been reached. Control rule are carried out for continuous and discrete time domains with similar performances. Hence applicability of this actuation and control method have been stated. • Active Roll Fin Stabilizer is designed for DTMB 5415 in different sea states. • H ∞ Optimal Control are applied to mitigate of the roll motion of the warship. • Control Method is applied both continuous time and discrete time. • Actuator saturation problem is taken account. • Actuator mathematical model is implemented to the roll motion mathematical model. • Suitability of the fin angles for different sea states is obtained. • Controllers damped roll motion amplitudes up to 90%. • Military standards mentioned by STANAG 4154 is met for DTMB 5415 Combatant warship.
