Design of Time-Varying Hybrid Zero Dynamics Controllers for Exponential Stabilization of Agile Quadrupedal Locomotion
This thesis explores the development of time-varying virtual constraint controllers that allow stable and agile gaits for full-order hybrid dynamical models of quadrupedal locomotion. Unlike time-invariant nonlinear controllers, time-varying controllers do not rely on sensor data for gait phasing …

Recurrent Gait of Anthropomorphic, Bipedal Walkers
This thesis explores the dynamics of two bipedal, passive-walker models that are free to move in a three-dimensional environment. Specifically, two rigid-bodied walkers that can sustain anthropomorphic gait down an inclined plane with gravity being the only source of energy were studied using …

ΠΕΡΙΟΔΙΚΕΣ ΚΑΙ ΑΣΥΜΠΤΩΤΙΚΕΣ ΛΥΣΕΙΣ ΓΥΡΩ ΑΠΟ ΑΣΤΑΘΗ ΣΗΜΕΙΑ ΙΣΟΡΡΟΠΙΑΣ ΣΤΟ ΠΡΟΒΛΗΜΑ ΤΩΝ ΤΡΙΩΝ ΣΩΜΑΤΩΝ
THE PERIODIC SOLUTIONS OF NON-INTEGRABLE DYNAMICAL SYSTEMS HAVE BEEN THE SUBJECT OF A GREAT DEAL OF RESEARCH, AND ARE OF PARTICULAR IMPORTANCE IN THE STUDY OF MECHANICAL SYSTEMS. A NON-INTEGRABLE DYNAMICAL SYSTEM CANNOT BE DESCRIBED BY ANALYTICAL METHODS AND NUMERICAL TREATMENT, WITH THE USE OF …
