AN EXTERNAL MODEL CONTROL-SYSTEM

A new observer-based approach to disturbance rejection and control in linear continuous systems is introduced. A recently developed techniqu e of continuous deadbeat observation is exploited to estimate the proc ess states and disturbance signal described by a known dynamic model. A realization condition in the form of linear algebraic equations is d erived. When there is no reliable disturbance model available, it is s uggested to use a neural network-based structure. An application examp le illustrates the feasibility of the approach taken.
