摘要:
对网络控制系统中的短时滞、长时滞、均方指数稳定和随机稳定作了定义,完善了长时滞网络控制系统的数学模型,设计了长时滞网络控制系统在状态反馈下的随机最优控制器,并证明了该最优控制律可使网络控制系统均方指数稳定和随机稳定.最后以不稳定的倒立摆为对象进行了仿真研究,仿真结果表明了本文方法的正确性和有效性.
Abstract:
The short delay, long delay, exponentially mean square stability and stochastic stability of networked control systems are defined in this paper. The mathematic model of networked control systems with long delay is perfected. This paper presents the design of controllers of networked control systems with long delay when the system has state feedback. The paper proves that the optimal control law can render networked control systems exponentially mean square stable and stochastically stable. In the end the simulation based on the unstable inverted pendulum is studied. The simulation results show that the proposed methods are correct and effective.
