Guaranteed Performance Control of Uncertain Linear Systems via Constant Gain State Feedback

고정이득 상태귀환을 통한 불확정 선형 시스템의 성능보장제어

This paper investigates the control problem which is specified by an uncertain linear system and a linear quadratic performance index. Only the size of parameter uncertainty is assumed to be given instead of its statistics. In addition, a mathing condition which constrains the system structure is assumed to be satisfied. The control law can be obtained by solving an LQ optimal control problem for a nominal system.
