摘　　要：本文介绍了两种离散模型参考自适应控制理论方法来实现对参数未知或慢时变的迟滞对象的控制。一种是把最小预测误差控制与合适的参数估计算法结合起来的方法。一种是基于波波夫超稳定理论得到的相应的自适应律,进而调节控制器参数的方法。这两种方法结构简单,易于实现。通过仿真可以得到这两种方法都能有效地实现对参考模型输出的跟踪,并且都可以克服一定的输出扰动。Introduce two kinds of discrete MRAC theories, they are used to realize the control of delay objects with unknown constant or slow time varying parameters. One method is to combine the minimum prediction error control with the appropriate parameter estimation algorithm.Another method is based on the theory of Popov super stability,the corresponding adaptive law is obtained to adjust parameters of the controller.The two methods structure simple and easy to implement.Through the simulation,we can know that the two methods can effectively achieve the tracking of the output of the reference model and can overcome some output disturbance more effectively.
