Abstract :
A novel discrete-time variable structure control technique is presented in this paper, for the control of uncertain continuous-time systems. The design algorithm makes also use of time delay control in order to estimate the effects of the system perturbations inside the switching region. The controller performances have been evaluated by simulation using a benchmark problem proposed in literature. A satisfactory behaviour is obtained also in presence of remarkable uncertainties, showing noticeable robustness with respect to parameter variations and external disturbances. Moreover, the time response can be shaped by the designer, properly tuning the control algorithm parameters
