Passivity Check of $S$-Parameter Descriptor Systems via $S$-Parameter Generalized Hamiltonian Methods

Passivity Check of S-Parameter Descriptor Systems Via S-Parameter Generalized Hamiltonian Methods

This paper extends the generalized Hamiltonian method (GHM) [1], [2] and its half-size variant (HGHM) [2] to their S-parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of S-parameter descriptorform models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable of accurately detecting the possible nonpassive regio...

Passivity Check of -Parameter Descriptor Systems via -Parameter Generalized Hamiltonian Methods

This paper extends the generalized Hamiltonian method (GHM) (Zhang et al., 2009; Zhang and Wong, 2010) and its half-size variant (HGHM) (Zhang and Wong, 2010) to their -parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of -parameter descriptor-form models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable o...

Robust Delay-dependent H∞ Filter for T-S Fuzzy Descriptor Time-delay Systems with Parameter Uncertainties ⋆

This paper deals with the delay-dependent robust H∞ filter for a class of Takagi-Sugeno (T-S) fuzzy descriptor time-delay systems with parameter uncertainties. The uncertainties in the system are timevarying and bounded. By simplifying the T-S fuzzy descriptor system to the time-delay system, and base on Lyapunov stability theory in time-delay system, a sufficient condition on the existence of ...

Parameter Estimation in Linear Descriptor Systems

Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differentialalgebraic equations in the continuous-time case. If some parameters in such models are unknown, one might need to estimate them from measured data from the modeled system. This ...
