The strong stability of the Perron-Frobenius semigroup and almost global attractivity
Pietro Lorenzetti, George Weiss
We discuss some useful properties of the solution map (flow) of a nonlinear dynamical system with a finite-dimensional state space. Then, we introduce the Perron-Frobenius semigrou…
Projected integral control of impedance passive nonlinear systems
Nicolas Vanspranghe, Pietro Lorenzetti, Lassi Paunonen +1
We propose an abstract framework for solving the constrained set-point tracking problem for impedance passive infinite-dimensional nonlinear systems. The class of systems considere…
PI control of stable nonlinear plants using projected dynamical systems
Pietro Lorenzetti, George Weiss
This paper presents a novel anti-windup proportional-integral controller for stable multi-input multi-output nonlinear plants. We use tools from projected dynamical systems theory…
The equilibrium points and stability of grid-connected synchronverters
Pietro Lorenzetti, Zeev Kustanovich, Shivprasad Shivratri +1
Virtual synchronous machines are inverters with a control algorithm that causes them to behave towards the power grid like synchronous generators. A popular way to realize such inv…
Saturating PI control of stable nonlinear systems using singular perturbations
Pietro Lorenzetti, George Weiss
This paper presents an anti-windup PI controller, using a saturating integrator, for a single-input single-output stable nonlinear plant, whose steady-state input-output map is inc…
