| 摘 要： | 研究了一类网络控制系统的时延补偿问题.由于系统的状态无法直接量测,因此本文针对短时延和长时延两种情况分别设计了状态观测器,所设计的观测器均满足分离原理.分析了系统的稳定性,在此基础上给出了这类网络控制系统输出反馈控制器设计的方法.仿真试验表明,所提补偿方案能够有效地补偿时延对系统性能的影响,且具有较高的补偿精度.

| Abstract: | Time-delay compensation of a class of networked control system was investigated. Because of the impossibility of measuring directly the system state, state observers were designed for both the cases of short-delay and long-delay, respectively. The separation principle held for the both observers designed. Finally, the system stability was analyzed, so that a method of designing the output feedback controller for such systems was presented. The result of simulation experiment showed that the influence of time-delay on system performance could be compensated effectively with a higher compensation accuracy by using the compensation scheme presented. |
