Abstract (EN): : In this paper we analyse the control of the total mass of compartmental systems, under the presence of uncertainties. We consider a control law that has a very good performance when applied to compartmental systems without uncertainties and show that, even when the system parameters are not exactly known, that good performance is maintained. In fact, for a wide class of compartmental systems of R3 , it is possible to prove that, when we apply that control law to the real system, the total mass of the system converges to a positive constant value, which depends on the parameter uncertainties and that can be made arbitrarily close to the desired mass, provided that the uncertainties in the parameter values are sufficiently small. The obtained results are illustrated by simulations for the control of the administration of the neuromuscular relaxant drug atracurium to patients undergoing surgery.
