A Track Keeping Variable Structure Fuzzy-PID Controller for Air Cushion Vehicle

全垫升气垫船航迹保持的变结构模糊PID控制

The first-order relative position equations are expanded as trigonometric series with eccentric anomaly as the angle variable. Except the terms of order one, the trigonometric series' amplitudes are geometric series, and corresponding phases are constant both in the radial and in-track directions.

通过将相对位置方程的径向和横向分量以偏近点角为变量展开为三角级数，发现除了一阶项外，三角级数的幅值为等比数列并且相角为定值。

2-D track-to-measurement association approach, a BP based Variable Structrue Interaction Multiple Model ( IMM), is proposed to simultaneously resolve the two most important uncertainties existed in the data association problem, i.e. measurement origin uncertainty and target motion uncertainty.

为了同时解决存在于航迹与量测互联问题中的两种不确定性：目标运动和量测源的不确定性，本文提出一种基于BP的变结构交互式多模型2D互联技术。
