本文研究一类Lipschitz非线性系统的动态输出反馈控制问题。首先,针对该系统设计了一个连续时间控制器,并且给出了系统稳定的充分条件。其次,针对该Lipschitz非线性系统提出一种新的事件触发机制,在该触发机制中引入了新的事件触发条件,并构建了事件触发控制下的闭环混杂系统。在混杂系统框架下建立了闭环系统稳定的充分条件。此外,给出了最小事件间隔的上界,以避免Zeno现象。最后,通过在神经网络系统和基因调控网络系统中的数值仿真验证了理论结果及所提方法的优越性。

Influence of boundary conditions and turntable speeds on the stability of hydrostatic oil cavity
Zhaomiao LIU, Chengyin ZHANG, Feng SHEN
《机械工程前沿(英文)》 2011年 第6卷 第3期 页码 359-368 doi: 10.1007/s11465-011-0222-2
The flow, bearing, and carrying capacity of the cycloidal hydrostatic oil cavity in hydrostatic turntable systems are numerically simulated, considering the rotation speeds of a turntable from 0 to 5 m/s and different boundary conditions. The vortex effect is weakened, and the stability of the oil cavity is enhanced with the increase in lubricant viscosity. However, the increase in inlet speed, depth, and inlet radius of the oil cavity causes the vortex effect to increase and the stability of oil cavity to reduce. With the increase in the oil film thickness, the carrying capacity of the oil cavity diminishes. The oil cavity pressure increases along the direction of the motion of the turntable; it is distributed unevenly because of the rotation of the turntable. With the increase in turntable speed, the location and size of the vortex scope in the oil cavity flow field and the strength of the vortex near the entrance gradually weaken and move away from the entry. The distribution of pressure is determined by the locations of the vortex. When the vortex is close to the wall, the wall pressure increases at its location. Otherwise, the wall pressure decreases first and then increases after the center of the vortex.
