This paper presents design, modelization and control of a new electropneumatic test bench. This latter has been designed for many applications given that it allows high accurancy control and dynamic perturbation force. In fact, the main originality (with respect to previous test benchs) of this test bench is that it is composed by two actuators, the first one being controlled in position, the second one generating perturbation forces. This latter one allows to evaluate the performance of control laws with respect to dynamical forces.
