Dynamic Modeling and Simulation of Servo System for Ship-borne Turret Equipment

doi:10.3969/j.issn.1000-1093.2019.04.018

Abstract

Abstract: A kinematics and dynamics model of a ship-borne turret equipment (STE) was constructed using coordinate transformation principle and Lagrange dynamic equations. The proposed model is used to analyze the influence factors on servo torque of STE in servo control. The servo control process of STE under different swing angles and target motion state was simulated, and the influences of swing angles and target motion state on servo torque were analyzed quantitatively. The simulated result shows that the servo torque varies almost linearly with the change in the amplitude and period of swing angle, and the effect of period is more obvious. When the amplitude of swing angle is increased by 1 degree, the servo torques of azimuth and elevation axes are increased by about 12% and 2%， respectively. When the period is increased by 1 s, the servo torques of azimuth and elevation axes are decreased by about 28% and 6%, respectively. The impact of the phase difference between swing angles on servo torque is complicated, and therefore the different intervals of phase difference need to be analyzed. Compared with the stationary state, the target motion causes the increase in the servo torque, and the impact of acceleration on servo torque is more evident. Key
