A tracked wing sale model and trials of discrete controls

Discrete-valued solutions were derived as the necessary condition for optimum control theory of a nonlinear switching system for when the manipulated variable was not included in the evaluation function. It was not possible to specify the optimal switching timing using this model. This new control method is different but similar to previous bang-bang control methods. A single wing sail model was loaded on a cart with four wheel casters and straight line test runs were performed on a track to determine the effectiveness of discrete switching control. The experimental investigation of the discrete switching control of our model was not successful on a two-dimensional track but was successful on a one-dimensional track.
