模型参考自适应控制系统已较广泛地应用于工业过程，其设计方法有的比较成熟，有的还正在发展，有待完善〔１〕。模型参考自适应控制系统的设计关键在于参考模型的给出。本文针对实际过程的特点，将一些复杂高阶系统简化为一类时滞系统。（即：一阶加纯滞后或二阶加纯滞后），并且提出了时滞系统的模型参考自适应控制的设计方法。仿真证明，该方法设计的自适应控制系统具有很好的鲁棒性，可广泛地应用于一般过程控制取代ＰＩＤ控制器。
Model reference adaptive control system has been more widely used in industrial processes, some of its design methods are more mature, and some are still under development, to be improved [1]. Model reference adaptive control system design is the key reference model given. In this paper, according to the characteristics of the actual process, some complex high-order systems are reduced to a class of time-delay systems. (Ie, first order plus lag or second order lag), and the design method of model reference adaptive control for time-delay systems is proposed. Simulation results show that the adaptive control system designed by this method has good robustness and can be widely used in general process control instead of PID controller.
