摘　　要：在基于紧格式线性化方法的无模型自适应控制算法(Model-free Adaptive Control Based on Tight Format Linearization,TFL-MFAC)的基础上,针对大时间滞后的特点,提出针对大时滞对象的MFAC改进算法(Improved MFAC on Large Time-delay System,LTDS-MFAC)。构造了大时滞对象并通过MATLAB仿真实验对改进MFAC算法的鲁棒性、抗干扰能力和跟踪能力进行分析。仿真实验表明了改进MFAC算法对大时滞系统控制具有更好的控制性能。According to the common characteristics of the controlled object with large time-delay, an improved algorithm based on the model-free adaptive control for large time-delay system（LTDS-IMFAC）is presented. The controlled objects with large time-delay are constructed, and MATLAB simulation experiments are worked, which analysis the robustness, an- ti-interference ability and tracking capabilities of the algorithm of LTDS-IMFAC. The simulation results show that the im- proved algorithm has better control performance for large time-delay objects.
