Abstract :
The problem of discrete-time adaptive stabilization under full-state feedback control is considered under weaker assumptions than the prior literature. The main result is based on a gain update law involving a step-size function. The formulation generalizes and unifies prior results based on quadratic and logarithmic Lyapunov functions.
