Disturbance decoupling by measurement feedback for SISO nonlinear systems
The measurement feedback disturbance decoupling problem of nonlinear systems with single-input/single-output and single measurement is considered in this paper. Necessary and sufficient conditions are given for disturbance decoupling by static measurement feedback. New necessary conditions and sufficient conditions are presented for disturbance decoupling by dynamic measurement feedback.
