摘要
对于存在时延和数据包丢失的广义网络控制系统,考虑数据包丢失率一定,网络诱导时延小于一个采样周期,通过对系统建模,把其转换为异步动态系统,给出指数稳定的充分条件,同时获得使系统稳定的动态输出反馈控制律。最后通过仿真实例表明方法的有效性。
The model and the stability of the networked control system with time delay and data packet dropout are studied in this paper.Based on the fixed rate of the data packet dropout,the networked control system is modeled as an asynchronous dynamical system（ADS） with rate constraints on events.The sufficient condition to the exponential stability of the networked control system is derived from the conclusion of the ADS.Simulation result show the validity of the method.
