fractal time-varying dimension 分形时变维数
time-varying dimension characteristics 时变维数特征
The concept of varying-time dimension is presented and the original fractional Brownian motion model is extended to be a locally self-similarity stochastic process.
提出了时变维数的概念，对原有分数布朗运动模型加以拓展，使其成为具有局部自相似性的随机过程。
The full-dimension state observer and reduced-dimension state observer are developed respectively. The control law is time-varying linear state feedback.
状态观测器的设计分为全维状态观测器和降维状态观测器，控制规律为时变的线性状态反馈。
