摘　　要：针对前向通道和反馈通道同时存在有界时变时延的网络控制系统,提出一种改进的线性自抗扰控制方法。利用Matlab/Simulink和TrueTime对网络环境下的直流电机控制系统进行仿真,验证了所提出方法的有效性及其控制系统良好的抗干扰能力和鲁棒性。This paper proposes a modified linear active disturbance rejection control approach for the networked control system with double sided bounded long network induced delays. Based on the MATLAB/Simulink and TrueTime toolbox, the effectiveness of the modified LADRC approach is demonstrated by the simulation results of a network based DC motor control system, and its excellent robustness and disturbance rejection ability of the NCS are also verified.
