查询词典 disturbances

One of the key issues in the design of fault diagnosis scheme is the effect of modelling uncertainties and disturbances. By using neural networks observer or approximator, the fault detection and diagnosis strategy for a class of nonlinear systems with modelling uncertainties are investigated.

而非线性系统故障诊断算法的鲁棒性则是一个极其关键的问题，本文主要针对非线性系统，进行了基于神经网络的鲁棒故障诊断方法研究。

Moreover, the mean-square tracking error can be made arbitrarily small by choosing some design parameters appropriately. Even with unmodeled dynamics and bounded disturbances presented the controller has good robust performance without need of correct dynamic model and parameter estimation.

并且这种控制器的设计不需要有精确的系统动态模型，不需要未知参数来满足线性依赖条件，不需要具体的系统参数估计，即使存在未建模动态和有界扰动，系统仍然具有很好的鲁棒性。

So it is of great significance to cancel or attenuate the effect of exogenous disturbances, both in theory and practice.

因此，在具有时滞的离散不确定系统中，如何设计控制器消除或减小扰动对系统的影响，无论在理论上还是在实践中，都是很有意义的研究课题。

The nonlinear stability of three-dimensional disturbances for the Blasius boundary layers is studied. We adopted here the high accuracy method of using the expansions in orthogonal functions along the normal direction and the effective algebraic mapping to deal with the problem in the infinite region. The initial solutions of two-dimensional harmonic waves are given by Landau expansion, and the mean-flow-distortion is calculated by the approximation equation.
