Global Stabilisation of Underactuated Mechanical Systems via PID Passivity-Based Control
Jose Guadalupe Romero, Alejandro Donaire, Romeo Ortega
In this note we identify a class of underactuated mechanical systems whose desired constant equilibrium position can be globally stabilised with the ubiquitous PID controller. The…
A tool for stability and power sharing analysis of a generalized class of droop controllers for high-voltage direct-current transmission systems
Daniele Zonetti, Romeo Ortega, Johannes Schiffer
The problem of primary control of high-voltage direct current transmission systems is addressed in this paper, which contains four main contributions. First, to propose a new nonli…
Energy Shaping Control of an Inverted Flexible Pendulum Fixed to a Cart
Prasanna S. Gandhi, Pablo Borja, Romeo Ortega
Control of compliant mechanical systems is increasingly being researched for several applications including flexible link robots and ultra-precision positioning systems. The contro…
Identification of Photovoltaic Arrays' Maximum Power Extraction Point via Dynamic Regressor Extension and Mixing
Anton Pyrkin, Fernando Mancilla-David, Romeo Ortega +2
This paper deals with the problem of identification of photovoltaic arrays' maximum power extraction point---information that is encrypted in the current-voltage characteristic equ…
Improved Transients in Multiple Frequencies Estimation via Dynamic Regressor Extension and Mixing
Aranovskiy Stanislav, Bobtsov Alexey, Ortega Romeo +1
A problem of performance enhancement for multiple frequencies estimation is studied. First, we consider a basic gradient-based estimation approach with global exponential convergen…
