The problem of memoryless variable structure control (VSC) for a class of uncertain time\|delay systems is discussed in this paper based on VSC approach and Lyapunov stability theory. The obtained VSC controller guarantees the quadratic stability of switching function and can avoid the chatting. The upper norm bound of uncertainties can be estimated by the adaptive VSC. The simulation results show that the obtained results are quite effective and feasible.
