Abstract: This study presents a generalised procedure for designing sliding mode control of neutral systems with uncertain parameters. Based on the new sliding surface, a sliding mode controller is designed, by means of linear matrix inequality technique to deal with the unknown parameters in the neutral systems. The bounds of the unknown parameters should be known in advance. The Lyapunov stability theory is referred to prove that the neutral system is converged to zero equilibrium. An example is simulated to demonstrate the effectiveness and efficiency of the procedure.

Keywords: neutral systems; uncertain parameters; sliding mode control; SMC; parameter uncertainty; controller design; linear matrix inequalities; LMI; Lyapunov stability theory; simulation.
