Abstract

The control scheme is based on a Luenberger observer. The approach to adaptive control is based on the concepts of the model following controller and the estimation of a disturbance by an observer. The plant is represented by a model with a fictitious disturbance at the input, and an observer estimates the states and the disturbance. The controller uses the states given by the observer in a feedback loop to make the states of the plant follow the states of the model, and the fictitious disturbance in a feedforward signal in order to cancel it
