查询词典 bound norm

By exploiting the important properties of robot dynamics, the second strategy removes the requirement of a priori bound on parametrer uncertainty and weakens the restriction on external disturbance. The only requirement is to know an upper bound of the norm of inertia matrix, which is not necessary to be the smallest.

An equivalent condition for the singular discrete linear systems to be regular, causal, stable as well as the transfer function satisfying a prescribed H-infinity norm bound is obtained by means of linear matrix inequation method.

利用线性矩阵不等式方法，导出广义离散线性系统正则、因果、稳定且传递函数满足给定的范数界的等价条件。

In classic theory,it is held that, in Sobolev Space ［H1］3, there is the upper bound of the norm of the constant rotating flow of the incompressible viscous fluid between two closed surfaces. It is inversely proportional to the viscosity of the fluid, and it will go to infinity when the viscosity goes to zero.

经典理论认为，不可压缩粘性流体定常旋转流在Sobolev空间［H1］3中的范数的上界与流体粘度成反比，随着流体粘度的减小，这一上界会无限地增大。
