Error analysis and a new steering law design for spacecraft control system using SGCMGs
Single gimbal control moment gyros (SGCMGs) Attitude control Singularity analysis Steering law
2010/3/16
Based on the singular value decomposition theory, this paper analyzed the mechanism of escaping/avoiding singularity using generalized and weighted singularity-robust steering laws for a spacecraft th...
Numerical Study of Grid Distribution Effect on Accuracy of DQ Analysis of Beams and Plates by Error Estimation of Derivative Approximations
differential quadrature grid structure truncation error high-order boundary value problems
2000/6/28
The accuracy of global methods such as the di erential quadrature (DQ) approach is usually sensitive to the grid point distribution. This paper is to numerically study the e ect of grid point distribu...
