Robust circular pole assignment for a class of discrete interval systems

To a class of discrete interval systems, this paper introduces a class of method of designing the state and output feedback gain which place the closed-loop poles of a given discrete interval system inside a specified circular disc, in terms of LMIs. The reliable controllers of actuator failure model and sensor failure model are also presented in this paper. At the end of this paper, numerical examples are also given to illustrate the design procedures and their effectiveness.
