immersed manifold

A simple nonlinear control method to design the missile autopilot: (system) immersion and (manifold) invariance is presented.为了克服非最小相位特性造成的设计控制器的困难,介绍了一种新颖的导弹非线性控制算法——(系统)浸入和(流行)不变算法,将导弹的输出跟踪问题转化为系统的镇定问题。IL3汉语字典

Let X:M n→E N be a smooth immersion of Riemannian manifold (M n,g) into euclidean N-space, and <h> and H the length of the second fundamental form and mean curvature of the immersion X respectively.设Ｘ：Ｍｎ →ＥＮ 为黎曼流形（Ｍｎ ，ｇ）到欧氏Ｎ—空间的等距浸入，＜ ｈ ＞ 及Ｈ 分别表示浸入Ｘ 的第二基本形式的长度及平均曲率，本文将证明积分∫Ｍ ｎ ＜ ｈ ＞ ｎｄｖ 在保高斯映射的共形形变下是不变量。IL3汉语字典
