网络控制系统的补偿预估器设计及稳定性分析

针对网络控制系统中的网络时延和数据包丢失问题，提出了在网络控制系统的控制器节点使用补偿预估的方法，以提高控制系统的性能.补偿方法针对网络时延，预估方法针对数据包丢失.通过构造增广状态向量，建立了统一的系统模型，当时延小于一个采样周期且数据包传输率一定时，将使用了补偿预估方法建模的该系统看作是具有两个事件的异步动态系统，并推导出系统指数稳定的充分条件.仿真结果表明，所提出的方法能有效提高控制系统的性能.

Design and stability analysis of compensator and estimator for network control system

For the network-induced delay and packet dropout in network control system(NCS),a combination of compensation and estimation methods in the controller unit to improve the performance of control system was proposed.The compensation method is for the delay and the estimation is for the packet dropout.The uniform model was established through constructing the augmented state vector.When the delay is less than a sampling period and the packet is transmitted at a fixed rate,the system obtained using the compensa...
