针对具有二阶非完整约束特性的常规水面船舶,进行航迹跟踪控制设计。利用基于动态非线性滑模分解迭代设计的增量反馈控制方法,在船舶有一定进速的条件下仅利用舵设备即可完成欠驱动船舶的路径跟踪。该算法无需对不确定模型的参数或风、流干扰进行估计,并解除了要求参考航向已知和角速度持续激励的限制条件,能够同时进行直线和曲线的航迹跟踪。对“育龙”轮的非线性水动力模型仿真结果表明,控制器对系统参数摄动及外界干扰不敏感,具有强的鲁棒性。
針對具有二階非完整約束特性的常規水麵船舶,進行航跡跟蹤控製設計。利用基于動態非線性滑模分解迭代設計的增量反饋控製方法,在船舶有一定進速的條件下僅利用舵設備即可完成欠驅動船舶的路徑跟蹤。該算法無需對不確定模型的參數或風、流榦擾進行估計,併解除瞭要求參攷航嚮已知和角速度持續激勵的限製條件,能夠同時進行直線和麯線的航跡跟蹤。對“育龍”輪的非線性水動力模型倣真結果錶明,控製器對繫統參數攝動及外界榦擾不敏感,具有彊的魯棒性。

The path following control problem was concerned for conventional surface ships with second order nonholonomic constraints.An feedback algorithm was presented by using in-crement feedback control method based on dynamic nonlinear sliding mode.Without estimation of systemic uncertainty and disturbances , the underactuated path following control objec-tive could be achieved by single input of rudder angle when the ship was proceeding at a forward speed .The known refer-ence orientation and the yaw velocity PE ( persistent excita-tion) conditions were not required , so the controller can also be used for way points tracking .Computer simulation on a full nonlinear hydrodynamic ship model of M .V.YULONG show the effectiveness and robustness of the proposed controller .
