Abstract: This paper presents sliding mode tracking control for a class of uncertain nonlinear systems with unknown parameters and system states. The sliding mode tracking controller with the differential evolution (DE) algorithm using integral-chain differentiator (ICD) is designed for the trajectory tracking in uncertain nonlinear systems. The ICD added into the sliding mode tracking systems provides the estimation of unknown states. The DE optimisation algorithm on the basis of ICD realises the unknown parametric identification in the limitation of unknown system states. The simulation is implemented to illustrate that the combined control scheme achieves high precision tracking performances.
