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。
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。
