Presentation
My name is Federico Cecati, I was born in L'Aquila (Italy) on the 4th May 1994. I have studied Control Engineering in University of L'Aquila and I got my master degree on October 2017. I studied piano as well in Conservatory of Music of L'Aquila, and I got my master degree in July 2017. Actually I am a PhD student in Chair of Power Electronic at the Kiel University with Prof. Marco Liserre. Since September 2020 I am in Aalborg University as a guest researcher. My research field is modelling and control of power electronic based power systems.

Master and Bachelor Thesis
The dynamic model of the robot is highly Nonlinear and hybrid as well. The impact of a foot with the ground represents a hybrid transition which changes intantaneously the state of the system. The used control stategy is based on feedback linearization: through a proper output definition, the gait problem can be reconducted to an output-zero-tracking problem, achieved with feedback linearization.
The ball-on-plate stabilization is a widely studied control problem. A ball lies on an actuated touchscreen platform, able to rotate around 2 axis: the stabilization consists in bringing the ball always in the center of the platform by tilting the platform in the proper way. In this thesis the ball-on-plate system is mounted on an industrial robot, which allows it to translate, obtaining an additional degree of freedom. The problem is dealt through a LQR controller applied to the linearized system model.
