抵御信息误差的动态输出控制

Dynamic Feedback Control Against Information Error

针对线性系统,采用更接近于实际的信息连续误差模型,利用线性矩阵不等式,给出了保证闭环系统渐近稳定的鲁棒动态反馈控制设计的线性矩阵不等式方法.所设计的控制系统不仅当系统信息不发生误差时可以保证系统的渐近稳定性,而且当系统信息产生误差时也保证系统的渐近稳定性.数例验证了文中所提出方法的设计过程,同时也展示了所提出方法的有效性.

For a class of linear system, a more practical model of information error is considred. We present an LMI（ Linear Matrix Inequality） based approach to design a robust dynamic feedback system which ensure the closed-loop system is asymptotically stable. The resulting control systems are robust in that they provide guaranteed asymptotic stability when the information error occurs. A numerical example is also given to illustrate the design procedures and their effectiveness.
