International Conference on Modelling, Identification and Control (ICMIC)
作者: Shuai Dong Zhishen Wang Lei Liu Liuli Ou Yongji Wang Key Lab for Image Processing & Intelligent Control Department of Control Science and Engineering Huazhong University of Science and Technology 1037 Luoyu Road Wuhan China
The H∞ approach is used for the clearance of flight control laws when some parameters in the flight control system vary in a certain range. The proposed H∞ approach is developed from general H∞ theory and is applie... 详细信息

Journal of Donghua University(English Edition) 2011年 第3期28卷 305-311页
作者: 陈文 方向忠 Shanghai Key Laboratory of Digital Media Processing and Transmissions Institute of Image Communication and Information Processing Shanghai Jiaotong University
A novel Bayesian super resolution (SR) algorithm based on the distribution of synthetic gradient is proposed. The synthetic gradient combines prior information in horizontal, vertical, and diagonal directions. Its dis... 详细信息
