Two-dimensional robust modified repetitive control for uncertain systems with disturbances

摘要: This study concerns the problem of disturbance rejection in a modified repetitive control system for linear uncertain plant. First, we present configuration system. It has new structure controller so as to improve feasibility system, and incorporates an equivalent input estimator it performance. Then, sufficient condition robust stability is derived terms matrix inequality using two-dimensional theorem Lyapunov theory. Finally, numerical example demonstrates validity superiority method.
