不确定系统的动态输出反馈镇定

Dynamic Output Feedback Stabilization of Uncertain Systems

研究一类单输入单输出非线性不确定系统的动态输出反馈镇定．当系统的确定性部分为最小相位系统时，提出了一种构造动态补偿器的新方法．与先前有关结果比较，该动态补偿器能适应更广类型的不确定性．

The paper considers the problem of dynamic output feedback stabilization of the single input single output uncertain system x = Ax + ξ1 (x) + B(u + ξ2 (x) ) .y = Cx. When Σ(C,A,B) is a minimum phase system with relative degree r>1, we present a new method of constructing a dynamic compensator such that the closed loop system is asymptotically stable. In comparison with previous results, the dynamic compensator can satisfy a wider class of uncertainties.
