摘要：

In this paper, the output feedback H-infinity controller design problem is addressed for linear systems subject to sensor nonlinearity. First, the existence condition of an output feedback controller is derived for systems with sensor sector nonlinearity. A design method for the output feedback H-infinity controller is proposed using a linear-matrix inequality, (LMI) based approach. The result is then applied to the, design of a regional output feedback H-infinity controller for the systems subject to sensor saturation. An LMI optimization based approach is proposed to computing the feedback matrices of the regional output, feedback W controller. At last a numerical example is presented to show the effectiveness of the results.
