Este trabajo desarrolla un control no lineal basado en modelo de referencia (MRC) y Lyapunov. Este MRC puede acomodarse a las variaciones de las frecuencias naturales de un brazo robotizado flexible cuando cambia la carga que se transporta en su extremo. Se utiliza el método de matrices de transferencia para obtener las formas modales, las frecuencias naturales y los rangos de variación de éstas. Con ellas se diseña el control MRC que de acuerdo con el segundo método de Lyapunov debe mantener la derivada de la función potencial del error entre los estados del modelo y los del sistema real negativa para que el sistema sea estable.

“…Contact-impact phenomena, which are present in almost all branches of engineering [23][24][25], are included in the latter. Contact forces and, specifically, impact events are responsible for the appearance of harmful phenomena in mechanical elements such as vibrations [26], wave propagation [27], fatigue [28], wear [29], crack [30], etc. Sudden changes take place during impact processes, in which the conditions of the mechanical system vary in short times.…”

In the present work, an introduction to the contact phenomena in multibody systems is made. The different existing approaches are described, together with their most distinctive features. Then, the term of coefficient of restitution is emphasized as a tool to characterize impact events and the algorithm for calculating the relative indentation between two convex-shaped bodies is developed. Subsequently, the main penalty contact models developed in the last decades are presented and developed, analysing their advantages and drawbacks, as well as their respective applications. Furthermore, some models with specific peculiarities that could be useful to the reader are included. The aim of this work is to provide a resource to the novice researcher in the field to facilitate the choice of the appropriate contact model for their work.

“…Impacts between bodies, which generate normal (impact/penetration) and tangential (friction) forces, are present in almost any mechanical phenomenon [23][24][25]. These events are responsible for different phenomena such as vibration propagation [26], damaging waves [27], fatigue in elements [28], wear [29], defects and so on. These collision phenomena between bodies produce swift forces of great magnitudes that dissipate large amounts of energy.…”

In the present work, different algorithms for contact detection in multibody systems based on smooth contact modelling approaches are presented. Beginning with the simplest ones, some difficult interactions are subsequently introduced. In addition, a brief overview on the different kinds of contact/impact modelling is provided and an underlining of the advantages and the drawbacks of each of them is determined. Finally, some practical examples of each interaction are presented and analyzed and an outline of the issues arisen during the design process and how they have been solved in order to obtain stable and accurate results is given. The main goal of this paper is to provide a resource for the early-stage researchers in the field that serves as an introduction to the modelling of simple contact/impact events in the context of multibody system dynamics.
