An "ideal" state feedback is first designed under certain mild assumptions. Then, a set of extended low-power high-gain observers is systematically designed, providing a complete estimation of the "ideal" feedback law. This yields a robust output feedback stabilizer such that the origin of the closed-loop system is semiglobally asymptotically stable, while improving the numerical implementation with the power of high-gain parameters up to 2.application/pdfen-AU© 2021 The authorsExtended state observer (ESO)invertibilitymulti-input–multi-output (MIMO)output feedback202110.1109/TAC.2021.30876572022-09-25
