Abstract
The design of state observer for a linear discrete or continuoustime uncertain system based on circularly regional pole assignmentis studied. Taking use of algebraic Riccati equations and linearmatrix inequalities, necessary and sufficient conditions for theexistence of the state observer based on circularly regional poleassignment is proposed and the formulation of the gain matrix ofthe state observer is given. The state observer given by us hasgood robustness, which is illustrated by examples.
