Algorithms for implementation of mechanical systems control
Author: Ibarra Gonzalez Haroldo Levi
Underactuated mechanical systems have less actuators than degrees of freedom
and have been of particular interest during last decades. There are many different
and well know underactuated mechanical systems that have been used to
apply new concepts in non-linear control. One of the most well known is the
Acrobot. The Acrobot is one of the simplest underactuated mechanical systems
and consists of two links with only one actuator between them; it is seen as
the simplest model for walking robots. In this thesis the model of the Acrobot
is extended to the 4-link in order to make a more realistic model for a legged
robot and the control will be done using the concept of virtual constraints. It
will be shown how the 4-link can be controlled to achieve a stable tracking of
the stable target walking trajectory. A model will be developed based on a real
4-link testbed to further practical implementation of the achieved control.
