In the methods of nonlinear analysis, along with the normalvariable stiffness methods, the improved BFGS method is used.
非线性分析的方法,除采用一般的变刚度法之外,还采用了改进的BFGS法。

Then, the normalvariable structure controller (VSC) and the adaptive variable structure controller with the estimation for the upper norms of uncertainties are presented.
所提出的近似自适应变结构控制器可以避免控制器中的不连续继电项,同时不必已知系统不确定性范数界。

In this paper, the distribution of quotient of normalvariable was derived, its application in analysis of environment factors was emphatically discussed, and an example was given.
