Low-Input Accurate Periodic Motion of an Underactuated Mechanism: Mass Distribution and Nonlinear Spring Shaping
Andrea Tilli, Elena Ruggiano, Alessandro Bosso +1
This work presents a control-oriented structural design approach for a 2-DOF underactuated mechanical system, with the purpose of generating an optimal oscillatory behavior of the…
Periodic Motion Optimization for an Underactuated Mechanical System through Synergistic Structure-Control Design
Andrea Tilli, Alessandro Bosso, Elena Ruggiano +1
In this work, we present the integrated structure-control design of a 2-DOF underactuated mechanical system, aiming to achieve a periodic motion of the end-effector. The desired be…
A Semi-global Hybrid Sensorless Observer for Permanent Magnets Synchronous Machines with Unknown Mechanical Model
Alessandro Bosso, Ilario A. Azzollini, Andrea Tilli
In this paper, we present a hybrid sensorless observer for Permanent Magnets Synchronous Machines, with no a priori knowledge of the mechanical dynamics and without the typical ass…
A Robust Sensorless Controller-Observer Strategy for PMSMs with Unknown Resistance and Mechanical Model
Alessandro Bosso, Andrea Tilli, Christian Conficoni
In this work, we present a mixed sensorless strategy for Permanent Magnets Synchronous Machines, combining a torque/current controller and an observer for position, speed, flux and…
