Abstract :
In the paper the structure of the H2 and H∞ suboptimal controllers is studied. In both cases the suboptimal controllers have the form of the dead-time compensator reminiscent of that of the famous Smith predictor. It is shown that unlike the H2 case, the H∞ dead-time compensator takes into account the exogenous disturbance signal. Since the disturbance is not measurable, the H∞ dead-time compensator “predicts” it on the basis of the worst-case scenario
