Abstract
In this paper we address the problem of friction compensation in a pneumatic control valve. It is proposed a nonlinear control law that uses algebraic estimators in its structure, in order to adapt the controller to the aging of the valve. For that purpose we estimate the valve parameters, including friction, online. The estimators and the controller are validated through simulations
