This paper presents a study of an electropneumatic system composed of two electropneumatic interfaces and a pneumatic cylinder. The model used is a simplified nonlinear model which takes into account the main nonlinearities. The main goal is to prove that the process with two controls can be made asymptotically stable by means of a regular (i.e., at least of class state feedback. To illustrate the performances obtained, with the proposed control, simulation results are given. [S0022-0434(00)01303-4]
