Abstract The paper contributes to unveil how drivers—either human or not—may lose control of road vehicles after a disturbance. First, simple vehicle-and-driver model is considered: Its motion characterized by the existence limit cycles whose amplitude depend on vehicle forward velocity (both oversteering and understeering may exibit this property). Such are originated Hopf bifurcation occurrin...

In this paper, the robust stability analysis of a fuzzy vehicle lateral system with perturbed parameters is presented. Firstly, the fuzzy controller can be linearized by utilizing the describing function method with experiments. After the describing function is obtained, the stability analysis of the vehicle lateral control system with the variations of velocity and friction is then carried out...

This paper reports a stable online adaptive identification technique for the identification of finite-dimensional dynamical models of dynamically positioned underwater robotic vehicles. Proofs for the identifier’s global stability, and for the input-tostate stability of this class of plants are reported. A direct comparison of the adaptive identification method to a conventional, offline, least...
