摘要
针对船舶减摇鳍控制系统 ,考虑到船舶在大风浪中运动时 ,系统不可避免地存在非线性和不确定性的影响 ,将作者提出的对于不确定非线性系统的变结构自适应鲁棒控制策略应用于船舶减摇鳍控制系统 .经仿真试验表明 ,该控制策略对于船舶减摇鳍非线性控制系统是十分有效的 ,特别是鲁棒性能令人满意 .
In this paper, a variable structure adaptive robust control algorithm is presented for a class of uncertain nonlinear systems when assuming unknown control gain parameters of the system and unknown bound of uncertainty. And the method described is applied to ship roll stabilization by fin control system. It is shown that it makes the designed system guarantee the performance of robustness with respect to the perturbations and uncertainties.
