Abstract :
A method is presented for designing robust reference governors for uncertain discrete-time linear systems in the presence of unknown but bounded input disturbances and pointwise-in-time input and/or state constraints. A reference governor is a nonlinear device which is added to a primal compensated linear system in order to modify, when necessary, the reference signal in such a way the constraints are enforced and the compensated system maintains its linear behaviour. The present solution extends previous results in various directions
