【摘要】 介绍了网络控制系统,Truetime工具箱以及安装过程。结合使用Jitterbug工具箱用LQG算法对3个倒立摆网络控制模型进行了仿真实验,运用EDF算法和RM算法进行仿真对比。从结果可以看出,3个倒立摆都得到了很好的控制,EDF的总体控制性能要优于RM控制算法。从丢包率和网络传输速度两方面研究了网络服务质量(QoS)对控制性能的影响。采用PID算法控制单回路的直流电机模型,丢包率较小,传输速率较快,控制性能较好。更多还原

【Abstract】 The networked control system,Truetime toolbox and its installation are in troduced.Combined with Jitterbug toolbox,network control models of three pendulums are simulated by using LQG algorithm.And the simulation results are contrasted by EDF algorithm and RM algorithm.The results show that the three pendulums are controlled well,and the performance of EDF is better than RM.The effect of QoS on control performance is discussed in loss ratio and network transfer velocity.The PID algorithm control is used to control single circuit DC-motor,and the small loss ratio,quick velocity and good performance are obtained.更多还原
