Abstract :
An adaptive method for improved cost performance in nonlinear Lyapunov-based design is presented. The method is based on the idea of Lyapunov optimizing control and is discrete in nature. The goal of this method is to improve the cost performance in nonlinear systems when Lyapunov-based stabilizing controllers are used. The method takes advantage of Lyapunov stability techniques while adaptively choosing descent directions to provide a reduction in cost
