摘　　要：以大时滞过程为研究对象,对无模型自适应(MFA,M0del-freeAdaptive)控制器进行了仿真和实验研究,并与传统的PID控制器进行了比较,同时进行了鲁棒稳定性的研究。实验结果表明,无模型自适应控制器具有良好的输出跟踪性能,有很强的自适应能力和鲁棒性,能有效地控制复杂过程,特别在控制大时滞过程方面与传统的PID控制器相比,有着明显的优越性。A process with large time delay is selected as the process to cany out the simulation and experiment study by MFA controller, then comparative study with the PID controller is conducted. And the robustness of MFA is also analyzed. The results have shown that MFA has good behavior in output tracking, and it also has good robustness properties. It can be used to control the complex process with a better performance, it is especially good at controlling the large time delay process compared with PID controller.
