Interconnection of port-Hamiltonian systems and composition of Dirac structures
Port-based network modeling of physical systems leads to a model class of nonlinear systems known as port-Hamiltonian systems. Port-Hamiltonian systems are defined with respect t...

A minimum-time control strategy for torque tracking in permanent magnet AC motor drives
: A minimum-time torque control strategy for permanent-magnet ac motor drives is presented. The proposed solution is obtained by an ad-hoc procedure based on the computation of rea...

Input-to-state stability of switched systems and switching adaptive control
In this paper we prove that a switched nonlinear system has several useful ISS-type properties under average dwell-time switching signals if each constituent dynamical system is I...

Correlation-based tuning of decoupling multivariable controllers
The iterative method labelled Correlation-based Tuning (CbT) is considered in this paper for tuning linear time-invariant multivariable controllers. The approach allows one to tun...

Systematic ultimate bound computation for sampled-data systems with quantization
We present a novel systematic method to obtain componentwise ultimate bounds in perturbed sampled-data systems, especially when the perturbations arise due to quantization. The pr...

Stability analysis of systems with uncertain time-varying delays
Stability in presence of bounded uncertain time-varying delays in the feedback loop of a system is studied. The delay parameter is assumed to be an unknown time-varying function f...

Nonsmooth optimization for multiband frequency domain control design
Multiband frequency domain synthesis consists in the minimization of a finite family of closed-loop transfer functions on prescribed frequency intervals. This is an algorithmical...
