Then,two-dimensional model of grain flux in an electric field is presented by means of the concept and the law of viscoce fluid based on nonuniform density and viscosity of grain flow.
在对文献[2]中颗粒流量一维模型分析的基础上,考虑颗粒流密度的不均匀性和粘性,应用粘滞性流体概念及规律,给出电场中颗粒流量的二维模型。
The comparison principle of the multiple rational delays discrete systems and the frequency domain method are employed to reduce the multiple rational time delay discrete systems with interval coefficient to the multiple rational time delay in-varying discrete systems,and to study their delay-independent stability.
应用多组有理数时滞离散系统的比较原理和频域法,将多组有理数时滞区间系数离散系统化为多组有理数时滞定常离散系统,以判定其时滞无关稳定性,并举例说明了新定理的有效性和实用性。
Based on LMI, we give the sufficiency criterion about delay-independent stability and performance of persistent bounded disturbance rejection for time-delay systems by Lyapunov method.
基于LMI,我们利用Lyapunov函数方法给出了时滞系统的时滞无关稳定性及对持续有界扰动抑制性能的充分性判据。
