A ship course controller is designed for Norrbin nonlinear ship mathematical model with matching uncertainty. Combining the backstepping algorithm with the nonlinear damping algorithm to design controller, the nonlinear damping is used to cancel the uncertainty. The integral item is introduced in the design to improve the performance of the controller. Now, general ships can only use the electric gyrocompass to measure the course angle, but they have no equipments to measure the angular velocity, so in this article another ship course controller of output feedback is designed for Norrbin nonlinear ship, firstly the angular velocity is estimated by the observer and then the ship course controller is designed.

本文基于含有匹配不确定项的Norrbin非线性船舶数学模型，将backstepping算法和非线性阻尼算法相结合设计船舶航向控制器，利用非线性阻尼来抵消系统的不确定项，同时为了更好地改善系统的性能，在设计过程中引入了积分项；由于目前一般船舶只有电罗经用于测量船舶的航向角，还没有测量船舶航向角速度的设备，因此，针对Norrbin非线性船舶模型设计了一种输出反馈控制器，首先利用观测器对船舶航向角速度进行估计，然后再设计船舶航向控制器。

As one of Form-Position Errors, Positional Error does not only control single item but also Form Errors such as perpendicularity, parallelism, angularity, straightness. This paper studies the theory and technique of Error Separation.

在形位误差中位置度误差在控制单个要素或成组要素位置精度的同时，还综合控制了垂直度、平行度、倾斜度、直线度等误差项目，因此本论文重点研究讨论误差分离理论和分离技术在位置度误差评定中的应用。

The Apriori is an algorithm about the generation of association rule. Enlightened by the generation of candidate k-itemsets, k subsets of one item will be first find out, and then connected to get subsets of two items, and finally get the subsets of k-1 items. The algorithm can be used to find out the proper subset and to generate the protasis and apodosis of the association rule.

在关联规则--Apriori算法方面，主要是受Apriori算法中生成候选k项集方法的启发，提出首先找出k个只含1项的子集，然后将它们连接生成含2项的子集，直到最后连接成k-1项的子集为止的寻找真子集并生成关联规则前件、后件的算法。
