Abstract :
A modification of process-model control schemes is introduced. This modification consists in a periodic resetting of the initial condition of the predictor. It allows us to extend the use of these control laws to unstable linear systems with delay. The robustness of the scheme with respect to parameter uncertainty, delay uncertainty and external disturbances is shown. An illustrative example is presented
