针对网络系统具有长时滞和动态变化的特性，但PID控制器不能随着变化的网络环境在线调节参数的缺陷，引入模糊PID算法在线整定PID参数，通过模糊控制器自动调整PID参数。仿真实验结果表明，用该方法设计的控制器与PID算法相比，动静态性能更好。

With the characteristics of long time-delay and dynamic change in network system, PID controller can’t adjust parameters along with the change of network environment online, thus the paper introduced fuzzy PID algorithm to set PID parameter online, using the fuzzy controller to adjust automatically PID parameters. Simulation results show that comparted with PID algorithm, the dynamic and static performance is better than PID algorithm.
