摘　　要：针对网络存在时延和网络控制系统被控制对象无法直接测量这两种情况,提出了使用基于观测器的对象模型的网络结构,在此基础上研究了系统的稳定性。通过仿真实验,表明了稳定性条件的正确性与有效性,采用此结构系统具有很强的鲁棒性。For the plant state can＇t be measured directly and the networked control systems have delays, the observerbased networked control system structure of plant model was proposed. The stability problem was studied based on the design of the observer. Simulation results demonstrate that the proposed methods are feasible and effective, and the systems with this class structure is robust.
