中文摘要:分析穿浪双体船实际应用中存在的问题,给出穿浪双体船纵向运动控制模型,并基于滑模控制理论设计减纵摇控制器。为了克服传统滑模控制存在的高频抖振问题,对控制律中的符号函数进行柔化处理,取得良好的减摇控制效果。仿真结果表明了本文方法的有效性。

Sliding Mode Control of Longitudinal Motion for Wave-piercing Catamaran
Abstract:Its advantages, as well as disadvantages emerged in actual use for wave-piercing catamaran, is analyzed.The mathematic model for longitudinal motion control is given and a roll stabilization controller is designed based on sliding mode control theory. To overcome the defect of hige frequency chattering of conventional sliding mode control method, a revised switching term that can make the control signal become “soft” is used. The sliding mode controller designed here has perfect roll stabilizatin effect. Simulation results prove its effectiveness.
