中文摘要:
      提出一种NPCCS(网络化并联式串级控制系统)基本结构;针对网络时延的存在影响系统稳定性的问题,提出一种基于新型内模控制和Smith预估控制的NPCCS时延补偿与控制方法。以真实网络数据传输过程代替其间网络时延预估补偿模型,在满足被控对象预估模型等于其真实模型的情况下,可实现对网络时延的动态补偿与控制。仿真结果表明,系统具有良好的跟踪性能,较强的鲁棒性和抗干扰能力。
英文摘要:
      The basic structure of networked parallel cascade control systems is presented. Aiming at the problem of system stability caused by the existence of network delay, a new method of delay compensation and control is proposed for networked parallel cascade control systems based on new internal model control and Smith predictive control. The real network data transmission process replaces the network delay estimation compensation model, so the dynamic compensation and control of network delay can be realized when the predictive model of the plant is equal to the real model. Simulation results show that the system has good tracking performance, strong robustness and anti-interference ability.
