摘　　要：将跟踪微分器加入到无模型自适应控制器中,结合跟踪微分器与无模型自适应控制器的优点,设计出一种适合于诸如非线性、时滞、时变、强耦合等复杂系统的控制器。该控制器利用跟踪微分器安排过渡过程,实现了对强干扰、大时滞系统的快速、无超调控制,并且进行了与非线性PID(proportional integral derivative)控制器的对比仿真研究。仿真结果表明:带有跟踪微分器的无模型自适应控制器具有的优点,适合于处理带有强干扰以及时滞系统的控制问题。The paper presents that by combining tracking differentiator with model-free adaptive （MFAC） and joining their advantages, it is possible to design a controller fit for such eompli controller cated systerns as large-scale time delay system, time-variation system and strong coupling system. This controller realizes the fast and non-overshoot control on strong disturbance system and time delay system by arranging transitional process of tracking differentiator. The paper carries out a contrast emulation research between the MFAC with the tracking differentiator and the non-linear PID（ proportional integral derivative） controller. The emulation result indicates that the merit of the MFAC with a non-linear tracking differentiator is suit to deal with the control problem of strong disturbance and time delay.
