Abstract :
A new observer-based approach to perfect disturbance rejection in linear continuous systems is introduced. A technique of continuous deadbeat observation is exploited to estimate the disturbance signal described by a known dynamic model. A realization condition in the form of linear algebraic equations is derived. It is shown that the introduced disturbance rejection scheme can be used in combination with any conventional control technique such as stabilization or servo control
