基于特征建模理论,针对一类可由一阶特征模型描述的被控对象,设计一种新的自适应跟踪控制方法.通过参数整合,将系统特征压缩到一个时变参数中,进一步减少需估计的参数,更利于工程应用.利用李雅普诺夫方法,分析闭环系统的稳定性.最后,通过数学仿真验证了所提出方法的有效性. Based on the feature modeling theory, a new adaptive tracking control method is designed for a class of controlled objects which can be described by the first-order eigenmodel. The system features are compressed into a time-varying parameter by parameter integration to further reduce the need to estimate Which is more conducive to engineering application.The stability of the closed-loop system is analyzed by Lyapunov method.Finally, the effectiveness of the proposed method is verified by mathematical simulation.
