This paper describes the basic methods of the discrete transfer function from a continuous analogue, consideration of the use of real interpolation method in the sample. A current example is the comparison of methods of sampling. The work is done at the expense of grants under the program increase the competitiveness of TPU.
A nonlinear feedback system is designed and analyzed for a surface micromachined resonant accelerometer. For this, a brief illustration of the plant dynamics is given. In the analysis, the periodic signal in the nonlinear feedback loop is obtained by the limit cycle point, which is best approximated via the describing function method. This approach is reasonable in that the describing function method...
The dynamic performance and output power of two piezoelectric flags are greatly different from those of a single piezoelectric flag due to the coupling effect of each other. In this paper, the dynamic performance and energy harvesting ability of two piezoelectric flags in parallel arrangement in an axial flow are investigated using immersed boundary-lattice Boltzmann method coupled with Euler-Bernoulli...
Altitude regulation is a fundamental control problem of quadrotor UAVs (unmanned aerial vehicles) to ensure required performance for hovering and autonomous navigation. In this paper, under the assumption that the attitude inter loop has been well designed, the stability features of linear P+D+DD controller for altitude control are investigated. To handle the difficulty that the altitude velocity...
Fuzzy cognitive maps (FCMs), as an illustrative causative representation of modeling and manipulation of complex systems, can be used to model the dynamic behavior of the investigated systems. However, due to defects in expression and architecture, the traditional FCMs and most of their relevant extensions are not applicable to classification problems. To solve this problem, this paper presents an...
Reactive power plays a crucial role in power system operation and voltage management. However reactive power issues have rarely been considered in reliability evaluation of power systems. This paper investigates the effect of reactive power on reliability of the 220 kV Taiyuan Power System in Shanxi Province of China. Reactive power shortage and the associated voltage violations due to the failures...
Real-world workloads rarely saturate multi-core processor. CPU C-states can be used to reduce power consumption during processor idle time. The key unsolved problem is: when and how to use which C-state. We propose a machine learning prediction method and usage model. We evaluate this model with idle traces collected on dual-core and quad-core processor, and find this method can well predict CPUpsilas...
