Abstract :
A nonlinear robust state feedback controller for discrete-time uncertain systems is proposed. The uncertainties in the system must satisfy the matching condition, but only their bounds need to be known. The controller is designed via the second method of Lyapunov. The detailed derivation of the controller for single-input systems is given. The system response remains in the neighborhood of the zero state if uncertainties are small. The uncertainty bound for the stability condition is derived
