The control problem of a class of uncertain systems with no complete state availability is dealt with by means of second order sliding mode control techniques. In particular, a combined scheme, in which a 2-sliding mode differentiator and a 2-sliding mode controller are implemented, is used in order to solve the chattering avoidance problem for systems with relative degree two.

Abstract
The control problem of a class of uncertain systems with no complete state availability is dealt with by means of second order sliding mode control techniques. In particular, a combined scheme, in which a 2-sliding mode differentiator and a 2-sliding mode controller are implemented, is used in order to solve the chattering avoidance problem for systems with relative degree two.
