一种鲁棒模型参考自适应控制

A Robust Model Reference Adaptive Control

针对一类参数未知、具有常值扰动和未建模误差的线性离散系统，此文给出了一种模型参考间接自适应控制算法．该方法在未知系统高频增益符号时，可保证系统的非奇异性．同时，对于上述干扰具有鲁棒性．文中提出的自适应控制器可使闭环系统全局渐近稳定。

This paper presents a new robust MRAC scheme for discrete time systems with bounded disturbances and unmodelled dynamics. The control scheme guarantees globally asymptotical BIBO stability ofthe closed loop system. It requires neither introduction of persistent excitation nor a priori information onplant parameters and has no singularities.
