We discuss the modelling framework of port-Hamiltonian descriptor systems and their use in
numerical simulation and control. The structure is ideal for automated network-based …

The relation between passive and positive real systems has been extensively studied in the
literature. In this paper, we study their connection to the more recently used notion of port …

In this paper we revisit the Kalman–Yakubovich–Popov lemma for differential-algebraic
control systems. This lemma relates the positive semi-definiteness of the Popov function on …

We develop optimization-based structure-preserving model order reduction (MOR) methods
for port-Hamiltonian (pH) descriptor systems of differentiation index one. Descriptor systems …

In this paper, we introduce an innovative generalized Lyapunov theorem and a novel
bounded real lemma designed for continuous-time linear singular systems with Caputo …

This paper is concerned with the linear quadratic optimal control problem for impulse
controllable differential algebraic equations on a bounded half open interval. Regarding the …

This paper is concerned with the H∞ control problem for singular systems over finite
frequency ranges. The disturbance is assumed to be within low-/middle-/high-frequency …

This paper proposes a new generalized Lyapunov theorem and a new generalized
bounded real lemma for continuous‐time linear descriptor systems. First, we provide a …

In this paper, the iterative learning control problem is studied for a class of discrete singular
time-delay systems. Based on the equivalent restrict decomposition form of singular …

A class of F-passive descriptor systems is introduced, where F is also a descriptor system.
Time-domain and frequency-domain characterizations are presented, as well as properties …
