The invention relates to a small-waterplane-area catamaran head and tail stabilizing fin combined control method which comprises a small-waterplane-area catamaran, head fins are symmetrically arranged on the inner broadside of the head of the small-waterplane-area catamaran, tail fins are symmetrically arranged on the inner broadside of the tail of the small-waterplane-area catamaran, and the tail fins are symmetrically arranged on the inner broadside of the tail of the small-waterplane-area catamaran. A control system, an environment sensing sensor and a hull attitude sensor are carried on the small waterplane area catamaran; the head and tail stabilizing fin combined control method comprises eight operation steps. By obtaining an engineering empirical formula among the ship body resistance, the head fin attack angle and the tail fin attack angle and a longitudinal stability equation of the small-waterplane-area catamaran, the head fin and tail fin adjusting rotation angle value is obtained when the ship body resistance is the lowest, theoretical guidance is provided for stable navigation control of the small-waterplane-area catamaran, and the stability of the small-waterplane-area catamaran is improved. The longitudinal stability requirement of the ship can be met while the minimum resistance of the ship body is ensured by jointly controlling the head fin and the tail fin.
本发明涉及一种小水线面双体船首尾稳定鳍联合控制方法,包括小水线面双体船,所述小水线面双体船首部的内舷侧安装有对称布置有首鳍,小水线面双体船尾部的内舷侧安装有对称布置有尾鳍,小水线面双体船上搭载控制系统、环境感知传感器和船体姿态传感器;首尾稳定鳍联合控制方法包括八个操作步骤。通过得到船体阻力与首鳍攻角以及尾鳍攻角之间的工程经验公式以及小水线面双体船的纵向稳定方程,从而求得船体阻力最低时,首鳍与尾鳍调节转角值,为小水线面双体船稳定航行控制提供理论指导,通过联合控制首尾鳍即可达到在保证船体阻力最低的同时满足船舶的纵向稳定性需求。
