Abstract

This paper proposes a combined state feedback and control method based on the concept of variable structure systems (VSS). This method is defined as the smooth sliding mode controller and filter (SSMCF) and can be applied to a class of nonlinear systems. This paper provides a derivation of the SSMCF and defines the conditions for its stability. The experimental application of the SSMCF to a nonlinear hydraulic system is illustrated. The results indicate that the SSMCF maintains the advantages of VSS, such as fast response and robustness.
