A sliding mode controlled three wheels narrow vehicle for two passengers

This paper reports a sliding mode controlled three wheels narrow vehicle for two passengers. The whole system is a two-input two-output, eight-teen order dynamical system. In a first and simple design, a set of parameters that achieve an acceptable system performance under perturbations could be selected. Results where validated by simulation. However, the performance shown in a wide range of simulations run allows us to expect analytic proofs will be possible.
